20 POINTS. Select the correct answer. Considering only functions that have a rate of change less than that represented in the graph, which function has the greatest rate of change?

The function that has the greatest rate of change is "B"

Step-by-step explanation:

for finding the midpoint of any given 2 pair of points simply add the respective x coordinates with other x coordinate and the y coordinate with other y coordinate and divide them by 2

in your question it will be :

(3+1)/2 for the x coordinate of mid point i.e 2

[8+(-4)]/2 for the y coordinate of midpoint i.e 2

so coordinates of mid point of points (3,8) and (1,-4) will be (2,2)

x/3-10=8

x/3=18

x=48
