Let f(x, y)=x²-y³ - 6xy List the critical points: The critical point at the origin is a Select an answer The critical point with negative y value is a Select an answer Check Answer

Thank you!!

Find the critical point(s) of the function. f(x, y) = 2x²-y+4y (Give your answer as a comma-separated list of points in the form (*.*) if needed. Express numbers in exact form. Use symbolic notation and fractions where needed.) critical point(s): Compute the discriminant D (x, y). (Express numbers in exact form. Use symbolic notation and fractions where needed.) D(x, y) =

g(x) = 4 (1 + (1 over x) + (1 over x2)), [-5 , 5]   a.) Find the critical numbers and points of discontinuity. b.) Find the absolute extrema.
