For the rule $y=x^2−4$ , calculate the $y$ -values that complete the table below. Plot the points and connect them on a complete graph on graph paper. What does your graph look like?

IN (x)	$-3$	$-2$	$-1$	$0$	$1$	$2$	$3$
OUT (y)

Hint:

Substitute the values for $x$ into the given equation to find the values of $y$ .

IN (x)	$-3$	$-2$	$-1$	$0$	$1$	$2$	$3$
OUT (y)	$\boldsymbol{5}$	$\boldsymbol{0}$	$\boldsymbol{-3}$	$\boldsymbol{-4}$
