Evaluate the Function f(0)=x^2-4

$f (0) = x^{2} - 4$

Step 1

Replace the variable $x$ with $0$ in the expression.

$f (0) = {(0)}^{2} - 4$

Step 2

Simplify the result.

Raising $0$ to any positive power yields $0$ .

$f (0) = 0 - 4$

Subtract $4$ from $0$ .

$f (0) = - 4$

The final answer is $- 4$ .

$- 4$
