Seeking for guidance

[Lunto]

Hello, if someone could guide me in how to solve the first and the second it would be great. The third one is pretty easy (y=e^x^2 +c) and it's range is for any x (just need confirmation).
thanks

With the first i tried to move all the y to one side and the x to the other with no luck. Then i tried to replace y=vx, and again it brought me to nowhere..
At least you can tell me what kind of equation it is? And how you noticed it. Is it even linear?

I think that the question you have been given is that which one of the following differential equations can be solved? And your answer should be the third one.
