(1 point) Consider the function f(x, y) = 4x+ + 8y. List all critical points of f(x, y). If there are none, enter "none". If there is more than one, enter a comma-separated list of ordered pairs, e.g., "(1,2), (3,4). (5,6)" Critical points are List all critical points of f(x,y) which are local maxima. If there are none, enter "none". If there is more than one, enter a comma-separated list of ordered pairs, e... "(1,2), (3,4), (5,6) Local maxima occur...
4. (12 points) Find the critical points of f(x,y) = 2y3 + 3r? - 6xy and determine whether they are local minimum, maximum, or saddle points. For the critical points give us local extreme values, what are these extreme values (if any)?
