Question

What's the value of F(3) in the function below???

Answer 1

8, you plug 3 into x and you solve the exponent

Answer 2

Answer: B. 8.

Explanation:

The given function is :
`f(x)= 2^x`

Here , x= independent variable where we place the input value and f(x) = dependent variable where we get the output value.

Now , when we put x= 3 , we get

`f(3)=2^3= 2*2*2=8`

That means , the value of f(3) in the given function is 8.

Hence, the correct answer is B. 8.
