9-72.

Graph and shade the solution for the inequality below.

$y\le x^2+2x−8$

Choose values for $x$ and solve for $y$ in order to find points on the graph.

$0\le0^2+2(0)−8$

$0\le−8$

False. Therefore, it is not shaded on the inside of the graph.

Test a point on one inside of the graph. Try $(0,0)$.

Shade in the area opposite the point $(0,0)$.

Use the eTool below to help graph the inequality.
