Respuesta :

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

Answer: B. 8.

Step-by-step explanation:

The given function is  : [tex]f(x)= 2^x[/tex]

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

[tex]f(3)=2^3= 2\times2\times2=8[/tex]

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

Hence, the correct answer is B. 8.
