F (3) when f (x) = 2x + 2

Answer: f (x) = 8

Step-by-step explanation:

First you would plug in F (3) into the equation

replace the x with a three

f (x) = 2 (3) + 2

then multiply the 2 and 3 because when you see a number next to another number in parenthesis you multiply them

f (x) = 6+2

Then lastly you would add the result of your multiplied numbers with the two which gives you f (x) = 8.

f (x) = 8
