Answer:
[tex] \large \boxed{f( - 3) = 9}[/tex]
Step-by-step explanation:
Goal
- Find f(-3) with given function f(x)=x²
Given
[tex]f(x) = {x}^{2} [/tex]
Step 1
- Substitute x = -3 in the equation and replace f(x) to f(-3).
[tex]f(x) = {x}^{2} \\ f( - 3) = {( - 3)}^{2}[/tex]
Évaluate f(-3) as we get:
[tex]f( - 3) = 9[/tex]
Hence, the value of f(-3) is 9.
