The equation and graph show the distance traveled by a minivan and a puck truck in miles, y, as a function of time in hours, x.
The rate of change of the pickup is greater than the rate of change of the minivan
How to compare the rates of change?From the question, we have the graph that can be used in our computation:
On the graph, we have the following points
(x, y) = (0, 0) and (1, 50)
The equation of the proportional relationship is then calculated as
y = Y/X * x
Where
(X, Y) = (1, 50)
Substitute the known values in the above equation, so, we have the following representation
y = 50/1 * x
Evaluate
y = 50x
This means that the rate of the pickup is 50 miles per hour for the pickup
For the minivan, we have
y = 45x
This means that the rate of the pickup is 45 miles per hour for the minivan
50 is greater than 45
Hence, the rate is greater

How do you describe the transformation of a function?
The transformation of function is the process of modifying the existing graph of a function.
We know that in a function transformation, the graph of parent function either moves to left/right/up/down or resizes or reflects. There types of function transformations are: Translation, Dilation and Reflection
There are two types of translations of functions.
1) Horizontal translations: a function y = f(x) into the form y = f(x ± m)
if m > 0, then the function f(x ) moves to the left side by 'm' units.
if m < 0, then the function f(x) moves to the right by 'm' units.
2) Vertical translations: a function y = f(x) into the form f(x) ± m
if m > 0, then the function f(x) moves up by 'm' units.
if m < 0, then the function f(x) moves down by 'm' units.
Similarly there are two types of dilations.
1) Horizontal Dilation: a function y = f(x) into the form y = f(kx)
2) Vertical Dilation: a function y = f(x) into the form y = k f(x)
In both the cases, if k > 1, then the graph stretches and if 0 < k < 1, then the graph shrinks.
In case of reflection transformation of function y = f(x),
y = - f(x) is the reflection with respect to the x-axis and y = f(-x) is reflection with resepct to the y-axis.
Therefore, in a function transformation, the original graph of function either moves to left/right/up/down or resizes or reflects.

How many turning points can a degree 5 function have?
A degree 5 function can have up to five turning points. These turning points are also known as stationary points, inflection points, or extrema.
A degree 5 function is a polynomial of degree 5. This means that it is a function of the form f(x) = ax^5 + bx^4 + cx^3 + dx^2 + ex + f, where a, b, c, d, e, and f are constants. The degree of a function is determined by the highest power of the variable in the equation. In this case, the highest power of x is 5, and so the degree is 5. A degree 5 function can have up to five turning points. These turning points are also known as stationary points, inflection points, or extrema. A stationary point is a point on the graph of the function where the slope of the graph is either 0 or undefined, and an inflection point is a point on the graph of the function where the concavity of the graph changes. In order for a function to have a turning point, the derivative of the function must equal 0 at that point, and the second derivative of the function must not equal 0. If the second derivative does equal 0 at the point, then the point is a point of inflection, rather than a turning point. The number of turning points of a degree 5 function can be determined by finding the number of real roots of the equation f'(x) = 0, where f'(x) is the derivative of the function f(x). Since the degree of the derivative of a degree 5 polynomial is 4, this equation will have up to 4 real roots. This means that the degree 5 function can have up to five turning points.

Two lines intersect at the point (1, 3).
The y-intercepts of the lines are 1 and 2.
What are the equations of the lines?
In the case of the two lines you described, the y-intercepts are 1 and 2, meaning that the lines cross the y-axis at the points (0,1) and (0,2), respectively.
To find the equations of the lines, you can use the slope-intercept form of a line, which is written as y = mx + b, where m is the slope of the line and b is the y-intercept. Since the lines intersect at the point (1,3), you can use this point and the y-intercept of each line to find the slope of each line.
For the first line, with y-intercept 1, the slope is given by the formula m = (y2 - y1) / (x2 - x1), where (x1,y1) is the given point (1,3) and (x2,y2) is the y-intercept (0,1). Plugging in these values, we get m = (1 - 3) / (0 - 1) = -2. So the equation of this line is y = -2x + 1.
For the second line, with y-intercept 2, the slope is given by the same formula, using the point (1,3) and the y-intercept (0,2). This gives us m = (2 - 3) / (0 - 1) = -1. So the equation of this line is y = -1x + 2.
Therefore, the equations of the two lines are y = -2x + 1 and y = -1x + 2.

How will you compare the graph of a function and the graph of its inverse?
The graph of a function and the graph of its inverse are reflected across the line y = x.
Connsider a function f(x).
The inverse of function f(x) is represented as f^-1(x).
The inverse of a function is a function that reverses the effect of the original function.
We know that if we take the inverse of function then the domain of a function will be the range of inverse function and the range of a function will be the domain for its inverse.
This means if the point (3, -6) is in the original function then itwill be represented by the point (-6, 3) in the inverse function.
Also, we can obtain the graph of an inverse function as a reflection of the graph of original function across the line x = y.
Hence, the inverse functions' graphs are reflections over the line x = y

Temperature is typically represented on a graph by plotting points along the vertical (y-axis) to represent the temperature. The horizontal (x-axis) is typically used to represent either time or location. Each point on the graph is a measurement of temperature at a specific moment in time or location. The data points can be connected with a line to create a line graph, which can show temperature trends over time or in different locations. If two sets of data are being compared, such as indoor and outdoor temperatures, two lines can be drawn on the same graph to compare the two. By looking at the graph, one can easily identify the highest and lowest temperatures, as well as any trends over time. Additionally, the graph can be used to identify when temperatures are above or below a certain threshold. Graphs can be used to quickly and easily represent data, making them a powerful tool in understanding temperature.

How does a graph of a linear equation in two variables look like?
The graph of a linear equation in two variables is a straight line.
The general linear equation in two variables is ax + by + c = 0, where a, b, c are constants. Also, a and b cannot both equal zero at the same time. In order to graph of a linear equation in two variables ax + by + c = 0, we simply assume a set of values for x and calculate the respective set of values for y.
So we have a set of coordinates (x, y). Now plot the points on graph and join them.
The graph formed will be a straight line.
The point at which the line (graph of a linear equation) crosses the y-axis is the y-intercept and the point at which the line (graph of a linear equation) crosses the x-axis is the x-intercept.

However, an open, or unshaded circle is typically used to represent the inequalities greater than or less than.
Now, the first part of the piecewise function states that;

Thus, it will be an unshaded circle pointing to the left direction indicating less than.
