    Vector-Valued Function

    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 zmax=2 and the point to be (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!!

    The maximum height occurs when t(2 - t) has it's maximum .......

    Hint: The function z = t(2 - t) is a parabola with maximum turning point at (1, 1) ......
