Question

Use the function below to find F(4).

Answer 1

Answer:

Therefore, the correct option is C) $\frac{256}{3}$

Step-by-step explanation:

We need to find the $F(4)$ of the given function $F(x)=\frac{1}{3}\times 4^x$

To find  $F(4)$ , Replace $x=4$ in $F(x)=\frac{1}{3}\times 4^x$

$F(4)=\frac{1}{3}\times 4^4$

$F(4)=\frac{1}{3}\times 256$

$F(4)=\frac{1}{3}\times 256$

$F(4)=\frac{256}{3}$

Therefore, the correct option is C) $\frac{256}{3}$

Answer 2

Replace all x's with 4's in the function:
$f(4) = \frac{1}{3} \times {4}^{4}$
Simplify/solve.
$= \frac{1}{3} \times 256$
$= \frac{256}{3}$
So, the answer is C.
