Question

Use the following graph of the function f(x) = 2x3 + x2 − 3x + 1 to answer this question:

What is the average rate of change from x = −2 to x = 0?

Answer 1

@bibby

Answer 2

rate of change : \(\dfrac{f(b)-f(a)}{b-a}\)

rate of change from x = −2 to x = 0? \(\dfrac{f(-2)-f(0)}{-2-0}=\dfrac{-5-1}{-2}=\dfrac{-6}{-2}=3\)

Answer 3

Thank you!!

Answer 4

One question how did you get the -5-1 at the top?
