y''=1

Answer 4

Zippy he could just find that answer using wolfram so I don't see how it is very helpful here.

Anyways you know openstudy's prime directive is to help the user or guide the user to the answer, not to just give the answer.

Answer 5

we need to find y' first
so differentiate both sides of the equality
(x^2-4x)'=(2y-2)'
