(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

If dy/dt = ky and k is a nonzero constant, than y could be

a. 2e^kty

b. 2e^kt

c. e^kt + 3

d. kty + 5

e. .5ky^2 + .5

Correct answer is b. 2e^kt

2. Relevant equations

3. The attempt at a solution

I don't really know what I should be doing. I have a feeling I have to work backwards, therefore do the integral of ky? But if that is the case, I have no idea how e^kt is created through that integral. 2e^kt reminded me of Ce^kt, but that doesn't have anything to do with this problem either.
