Question

Please help me out :( I’m so behind :((

Answer 1

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

Explanation:

To find f(4), '4' will need to be substituted in place of 'x'. Therefore:

`f(x)(1)/(3) * 4^(x)` becomes:

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

Simplify:

`f(4) = (1)/(3)* 256\\ \\f(4) = (256)/(3)`

Therefore, f(4) equals
`(256)/(3)`
