Graph Using a Table of Values f(x)=x^2-9

$f (x) = x^{2} - 9$

Substitute $- 2$ for $x$ and find the result for $y$ .

$y = {(- 2)}^{2} - 9$

Simplify ${(- 2)}^{2} - 9$ .

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

$y = 4 - 9$

Subtract $9$ from $4$ .

$y = - 5$

Substitute $- 1$ for $x$ and find the result for $y$ .

$y = {(- 1)}^{2} - 9$

Simplify ${(- 1)}^{2} - 9$ .

Raise $- 1$ to the power of $2$ .

$y = 1 - 9$

Subtract $9$ from $1$ .

$y = - 8$

Substitute $0$ for $x$ and find the result for $y$ .

$y = {(0)}^{2} - 9$

Solve the equation for $y$ .

Remove parentheses.

$y = 0^{2} - 9$

Remove parentheses.

$y = {(0)}^{2} - 9$

Simplify ${(0)}^{2} - 9$ .

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

$y = 0 - 9$

Subtract $9$ from $0$ .
