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
