Answer:

A. 3

Step-by-step explanation:

y = 2^x

y = 8

Plug y as 8 in the first equation.

8 = 2^x

Make the left side of the equation with a base of 2.

2^3 = 2^x

Cancel bases.

3 = x

Answer:

x=3

Step-by-step explanation:

f(x) = 2^x

2^3 = 2^x

The bases are the same so the exponents are the same
