The Attempt at a Solution
Well, I solved for the derivative, but I'm not sure if it was to any avail seeing as when I plug the point back in I do not get an answer choice.
I got:
dy/dx = (-2xy^(2) + 9x^2) / (3y + 2x^(2)y)
Did I solve the derivative incorrectly? Or is plugging in the point not the correct course of action? Thank you again for all your help, I've been struggling with this problem a lot and any guidance/explanation would be great!
