Why guess? Just solve the DE, it's separable.

That's what I was thinking... this class is so new to me and the instructor isn't always so good with teaching us all that we need to know. So I solved it and got 2ln(t) + C... this would be the one-parameter family?

Yes, and what is the parameter? In other words, which value do you change to get a different solution to that same differential equation?
