Ok, last one for tonight, i can't believe i am stuck on this one:
Find the maximum height above the-plane of a point on
![]()
So i get the answer to be $\displaystyle zmax=2$ and the point to be $\displaystyle (0, 0, 2)$ but this answer is wrong, i know it is .something that is simple that i cannot figure out.
Thanks for your time!!![]()
