When you are given a function and it asks you what f(a number) is then you plug in the number in the parentheses into everywhere you see x in the function equation.

Essentially this equation is saying that x is equal to 5

f(5)

f(x) = 3x + 2

f(x) = 3(5) + 2 ---> 15 + 2 ---> 17

so...

f(5) = 17

Hope this helped!

16 - 12x + 20

-12x + 36
