Question

PLEASE HELP?!?! :))
Find the x and y values at the minimum of 2x^2+xy+2y^2+3y+2
And find the x and y values at the maximum of
-3x^2+2xy-4y^2+2y+7

Answer 1

sounds like calculus. Did you find the derivative of
2x^2+xy+2y^2+3y+2

Answer 2

It looks like you have
f(x,y) = 2x^2+xy+2y^2+3y+2
and you need to find the partial derivatives fx and fy
set both = 0 and solve for x and y

Answer 3

is it ok if you can walk me through this process? pleasse? :)
