Question

Calculate the average rate of change for the given graph from x = –2 to x = 0 and select the correct answer below.

A.) -2
B.) 2
C.) 3
D.) 6

Answer 1

3

Explanation:

Answer 2

We need to find f(x) on those 2 points and than divide y length (f(x2)-f(x1)) with x lenght (x2 - x1) to find average

f(x = -2) = 0

f(x = 0) = 6

Avg = 6 / 2 = 3

Answer is C

We have to use absolute valuee for x distance because distance between x1 and x2 cannot be negative it can only be positive.
