**Problem Statement:**##2x^2 + y^2 = 4##

Max and min of

##4x + y^2## ?

**Relevant Equations:**F'(x) = 0

To find critical point

X = 0 -> y = +- 2

Y =0 -> x = +- ##\sqrt 2##

I input that

Find f(xy) = 4 and f(xy) = +-##4\sqrt 2##

To find with derivative i find both x and y are zero

The answer is wrong
