Post Body

Hey, first time asking a question here, question is from my homework I need to find the critical points (1 inside the range and 6 on the edge)

Of the function f= 9-10x x2 y2

In the area inclosed by y= -1 And y= -x2 10x-21

But i can't find all 6 critical points on the edge And tbh I don't really understand how to use Lagrange with multiple constraints

Would be glad if someone could shed some light on it
