4-22.

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$)

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

 IN $\left(x\right)$ $-$3 $-$2 $-$1 0 1 2 3 OUT $\left(y\right)$ 5 0 $-$3 $-$4

Graph the points and connect them with a continuous curve.
