Question

Calculate the average rate of change for the given function, from x = 8 to x = 5.

Answer 1

The answer for the slope is -4/3

Answer 2

The average rate of change from x=8 to x=5 can be calculated as:

$\frac{f(8)-f(5)}{8-5}$

f(8) = 0
f(5) = 4

Using the values we get:

$\frac{0-4}{8-5} \\ \\ -\frac{4}{3}$

So, first option gives the correct average rate of change from x=8 to x =5 for the given function.
