72 when  when x=0. \\
\text{(B)} &  \text{It has a minimum value of }

Hi Hugo!

Thanks for letting us know. It should display correctly now. (You might need to start a new attempt of your homework for it to show.)

$\begin{array}{ll} \text{(A)} & \text{It has a minimum value of } 72 \text{ when } x=0. \\ \text{(B)} & \text{It has a minimum value of } -9 \text{ when } x=9. \\ \text{(C)} & \text{It has a maximum value of } 72 \text{ when } x=0. \\ \text{(D)} & \text{It has a maximum value of } -9 \text{ when } x=9. \\ \end{array}$
