Question

7)

What is the average rate of
change for f (x) = -2% + 70 over the interval 2 = X = 6?
A)
-15
O0
-16
-30
D)
-32

Answer 1

A

Explanation:

Here [ a, b ] = [ 2, 6 ], thus

f(b) = f(6) = - + 70 = - 64 + 70 = 6

f(a) = f(2) = - 2² + 70 = - 4 + 70 = 66

average rate of change = = = - 15 → A
