Evaluate f(x)=-2^2

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

Simplify $- 2^{2}$ .

Raise $2$ to the power of $2$ .

$f (x) = - 1 \cdot 4$

Multiply $- 1$ by $4$ .

$f (x) = - 4$

$f (x) = - 4$

Subtract $f (x)$ from both sides of the equation.

$0 = - 4 - f (x)$

Rewrite the equation as $- 4 - f (x) = 0$ .

$- 4 - f (x) = 0$
