We have:

Substitute:

<em>multiply both sides by 4</em>
<em>subtract 81 from both sides</em>
<em>divide both sides by 4</em>

The turning point is (3,3). The x to make the absolute value negative would be 2. The ordered pair would then be (0,3)
-24.3 feet
-22.55-19.5 is -42.05
-42.05+ 17.75 is -24.3
