Evaluate the Function f(-2)=x^2-3

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

Step 1

Replace the variable $x$ with $- 2$ in the expression.

$f (- 2) = {(- 2)}^{2} - 3$

Step 2

Simplify the result.

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

$f (- 2) = 4 - 3$

Subtract $3$ from $4$ .

$f (- 2) = 1$

The final answer is $1$ .

$1$
