Question

20) Find the extreme points and values of the function
f(x, y) = x² + y2 + xy + x - 4y +5​

Answer 1

A difierentiable function f (x,y) has a saddle point at a ... Find the local extreme values of f (x,y) = x2 + y2 − 4y + 9. ... f (x,y) = x2 + (y − 2)2 + 5 is never less than 5, we see that the critical ... f (x,y) = xy − x2 − y2 − 2x − 2y + 4.

Answer 2

Answer:

Step-by-step explanation:

Find the extreme value of the function $$f(x,y)=x2+y2+xy+x–4y+5.
