The graph of a function g is shown below. Use the graph of the function to find its average rate of change from x = -4 to x = 2. Simplify your answer as much as possible.

Solution

Average rate of change = [ f(2) - f(-4) ] / ( 2- (-4) )

from graph f(2) = -4 ; f(-4) = 8

So,Average rate of change = [ -4 - 8]/[ 6]

= -12/6

= -2
