Best ResponseYou've already chosen the best response.2We cannot just give you the answer....but here is a quick hint f(x) f(3) what's different between those two? well...3...is in the place of x so in terms of your equations where you have f(x)= x²  x + 2 f(3) = (3)²  (3) + 2 you literally just plug 3 in for every 'x' that you see...can you solve this?

Best ResponseYou've already chosen the best response.0Okay, here's the equation: \[f(x) = x^2  x + 2\] You need to evaluate \(f(3)\). To do that, you rewrite the equation substituting (3) everywhere you see \(x\).
