Question

The function y = f(x) is graphed below.

What is the average rate of change of the
function f(x) on the interval

Answer 1

To the Echeveria bouts of the GH to the feet square is the G sciences aesthetic

Answer 2

average rate of change = - 15

Explanation:

the average rate of change of f(x) in the closed interval [ a, b ] is

`(f(b)-f(a))/(b-a)`

for the interval - 4 ≤ x ≤ - 2 , then a = - 4 and b = - 2 , so

f(b) = f(- 2) = - 20 ← point (- 2, - 20 ) on graph

f(a) = f(- 4) = 10 ← point (- 4, 10 ) on graph

average rate of change =
`(-20-10)/(-2-(-4))` =
`(-30)/(-2+4)` =
`(-30)/(2)` = - 15
