Question

What is the average rate of change for this quadratic function for the intervalfrom x 45 to 5432hsA 8B-8C. 16D-16

Answer 1

A. 8

Explanation:

We calculate the average rate of change by means of the two points located between x = -3 and x = -5.

The point are (-3, 1) and (-5, -15)

`c=(y_2-y_1)/(x_2-x_1)`

Replacing:

`c=(-15-1)/(-5-(-3))=(-16)/(-5+3)=(-16)/(-2)=8`

The average rate of change is 8
