Question

WHAT'S THE AVERAGE CHANGE?

Answer 1

Answer:

1) 2

2) 4

3) 8

Step-by-step explanation:

You must apply the following formula:

$\frac{f(x_2)-f(x_1)}{x_2-x_1}$

Substitute value, then you obtain:

x=1 and x=2

$\frac{4-2}{2-1}=2$

x=2 and x=3

$\frac{8-4}{3-2}=4$

x=3 and x=4

$\frac{16-8}{4-3}=8$
