All you have to do is plug in 3 for x. 9+3 is 12, and 12^2 is 144. Your answer is f(3) = 144.

²Ok, so when they say to find f(3) this just means that they want you to replace the x value with the number 3 and solve it that way.
f(x) = (9+x)²
f(3) = (9+3)²
f(3) = (12)²
f(3) = 144
Hope that helps :)
