I am looking for step-by-step instruction so that I can understand the material.

-I need to find the global maximum and minimum values of f : R ² R, f(x,y) = 10 x² y³ 6y³ on the

the region in R² given by the inequality x²+ 3y² 3.

If the global maximum and minimum values do not exist, can you please explain to me why that is the case?

thank you for your help.
