from x= -5 to x= -3?
A. 16
ОО
B. -8
C. 8
D. -16

Answer 1

8

Explanation:

The average rate of change is given by

f(x2) -f(x1)

---------------

x2-x1

x2 = -3 and x1 = -5

Looking at the graph

f(x2) = f(-3) = 1

f(x1)= f(-5) =-15

Substituting these values into the equation

1 - (-15)

---------------

-3 - (-5)

1+15

----------

-3 +5

16

----
