##2x^2 + y^2 = 4##
Max and min of
##4x + y^2## ?
 Homework Equations

F'(x) = 0
To find critical point
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
