Question

Find the average rate of change for the given function from x = −2 to x = 1.
someone help

Answer 1

what does y equal for each one

Answer 2

The average rate of change from x=a, to x=b is the slope between the two points \((a,~f(a))\) and \((b,~f(b))\).

This slope will be given by the following expression:

\(\displaystyle {\rm m}=\frac{f(b)-f(a)}{b-a}\) (where \(\rm m\) is the slope)
