Use the function below to find F(-4) F(x) = 2^x A. 1/8 B. -16 C. -8 D. 1/16

Question

Use the function below to find F(-4)


`F(x) = 2^x`

A. 1/8
B. -16
C. -8
D. 1/16

Answer 1

D

Explanation:

The question is on negative exponents

Given that;

F(x)=2^x

From the general formulae a^-n =1/a^n

Hence

F(-4)= 2⁻⁴

F(-4)= I/ 2⁴

=1/16
