    We 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?

    Okay, 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 \(x\).

    Remember, a negative number * a negative number gives you a positive number.

    \[f(x) =x^2-x+2\]

    f(-3)=(-3)^2 -(-3)+2 f(-3)=9+3+2 f(-3)=14

    f(-3)=(-3)^2 -(-3)+2 f(-3)=9+3+2 f(-3)=14 so 14 is the answer?
