Question

Find f(3) for f(x)=1/2(4)^x

Answer 1

The answer is 32

f(x)=1/2(4)^x

f(3)=1/2(4)^3

f(3)=1/2(64)

f(3)=32

Answer 2

f(x) = 1/2(4)^x

Plug in 3 for x

f(3) = 1/2(4)³

Cube 4.

4³ = 4 x 4 x 4 = 64

f(3) = 1/2(64)

Multiply 64 with 1/2 (or divide by 2)

f(3) = 64/2

f(3) = 32

f(3) = 32 is your answer

hope this helps
