Question

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

Answer 1

$f(3)= \frac{1}{3} (4)^3$
$f(3)= \frac{1}{3} (64)$
$f(3)= \frac{64}{3}$

Answer 2

For given function  $f(x)=\frac{1}{3}(4^x)$, f(3) = 21.33

What is a function?

• "It defines a relation between input and output."
• "In function, for each input there is exactly one output."

For given question,

We have been given a function $f(x)=\frac{1}{3}(4^x)$

We need to find the value of f(3)

This means we need to find the value of given function  $f(x)=\frac{1}{3}(4^x)$ for   x = 3

For x = 3,

$\Rightarrow f(3)=\frac{1}{3}(4^3)\\\\\Rightarrow f(3)=\frac{1}{3}(4\times 4 \times 4) \\\\\Rightarrow f(3)=\frac{1}{3}\times 64\\\\\Rightarrow f(3)=\frac{64}{3}\\\\ \Rightarrow f(3)=21.33$

Therefore, for given function  $f(x)=\frac{1}{3}(4^x)$, f(3) = 21.33
