Answer:


\large \boxed{f( - 3) = 9}

Explanation:

Goal

  • Find f(-3) with given function f(x)=x²

Given

  • Quadratic Function


f(x) = {x}^(2)

Step 1

  • Substitute x = -3 in the equation and replace f(x) to f(-3).


f(x) = {x}^(2) \\ f( - 3) = {( - 3)}^(2)

Évaluate f(-3) as we get:


f( - 3) = 9

Hence, the value of f(-3) is 9.
