Question

Find the derivative of the function, xy-x-12y-3=0.

Is the answer -14,I got this from 1-1-12=0, which solves to -14.

Answer 1

Don't you have to do implicit differentiation?

Answer 2

Do you want dy/dx or dx/dy?
The answer of -14 makes no sense at all. Do you understand what a derivative is? It is the rate of change of a function. In this case, they want a formula for it.
