Question

Use the function below to find F(4).

F(x)=1/3*4^x

A. 16/3
B. 64/3
C. 256/3
D. 8/3

Answer 1

Replace all x's with 4's in the function:

`f(4) = (1)/(3) * {4}^(4)`
Simplify/solve.

`= (1)/(3) * 256`

`= (256)/(3)`
So, the answer is C.

Answer 2

Therefore, the correct option is C)
`(256)/(3)`

Explanation:

We need to find the
`F(4)` of the given function
`F(x)=(1)/(3)* 4^x`

To find
`F(4)` , Replace
`x=4` in
`F(x)=(1)/(3)* 4^x`

`F(4)=(1)/(3)* 4^4`

`F(4)=(1)/(3)* 256`

`F(4)=(1)/(3)* 256`

`F(4)=(256)/(3)`

Therefore, the correct option is C)
`(256)/(3)`
