Question

Use the function below to find F(3). F(x) =4×(1/3)^x​

Answer 1

A.
`(4)/(27)`

Explanation:

Given function:

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

To find
`F(3)`

In order to find
`F(3)` we will plugin
`x=3` in the given function.

So,

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

Expanding the exponents

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

`F(3)=4*(1)/(27)`

∴
`F(3)=(4)/(27)`
