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

ANSWER:
A. 8
STEP-BY-STEP 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)
[tex]c=\frac{y_2-y_1}{x_2-x_1}[/tex]Replacing:
[tex]c=\frac{-15-1}{-5-(-3)}=\frac{-16}{-5+3}=\frac{-16}{-2}=8[/tex]The average rate of change is 8
