Question

Find f(-2) for f(x) = 2(4)^x

Answer 1

Answer:

f(- 2) = $\frac{1}{8}$

Step-by-step explanation:

To find f(- 2) substitute x = - 2 into f(x) , that is

f(- 2) = 2 $(4)^{-2}$ = 2 × $\frac{1}{4^2}$ = 2 × $\frac{1}{16}$ = $\frac{2}{16}$ = $\frac{1}{8}$

Answer 2

Answer:

2(4)^-2

=2/4^2

2/16

1/8
