Hi I would really appreciate if anyone could help me with the following exercises k, l, m, n. I cant seem to solve the derivatives to find the critical points. THANK VERY MUCH in advance.

You need to use partial differenitation for these problems, then solve for $\displaystyle \left( \frac{\partial f}{\partial x}, \frac{\partial f}{\partial y}\right) = \b{0}$
