In each of the question verify that the given functions (explicit or implicit) is a solution of the corresponding differential equation:

It is given that y =

Now, differentiating both sides w.r.t. x, we get,









Therefore, LHS = RHS


Therefore, the given function is the solution of the corresponding differential equation.
