Can someone please check if i have the right answer?
Use Lagrange multipliers to find max/min values of
f(x,y) = 3x+y
subject to the constraint:
I got max at (2,-4) with a value of 2
min at (-2,4) with a value of -2
I have gone through the problem heaps and keep getting that answer. But when i graph the two functions on a graphing program these points don't look like the max/min values of the intersections...
Please if anyone could help that would be great, thanks!
