Calculus
Let me try to ask this question a different way:
4x^2+2x+xy=12 and y(2)=4 find y(prime)(2) by implicit differentiation.
I can differentiate it to
8x+2+y+xy(prime)=0
I don't know what to do with the y(2)=4 after this point.

Find d^2y/dx^2 by implicit differentiation. x^(1/3) + y^(1/3) = 4 I know that first you must find the 1st derivative & for y prime I got 1/3x^(2/3) + 1/3y^(2/3) dy/dx = 0 Then for dy/dx I got dy/dx = [1/3x^(2/3)] /
