Question

What is the average rate of change for ƒ(x) = −3x + 1 over the interval −2 ≤ x ≤ −1?

Answer 1

Answer:

The average rate of change is -3

Step-by-step explanation:

we have

$f(x)=-3x+1$

This is a linear function in slope intercept form  $f(x)=mx+b$

where

m is the slope

b is the y-intercept

In this problem

The slope is equal to

$m=-3$

Remember that

In a linear function the average rate of chance is a constant and is equal to the slope of the linear function in any interval

therefore

The average rate of change is -3

Answer 2
