# WebWork Antiderivatives #13

I noticed that a number of you have already finished most of the WebWork assignment on antiderivatives and have started on the others that are due next week. Good job! I received a question about #13 and thought the rest of you might like a hint.

In the other exercises that we’ve seen where we’re given $f''(x)$ and asked to find $f(x)$, we’re also given one initial condition for $f'(x)$ and one initial condition $f(x)$. Here, instead we’re just given two conditions that $f(x)$ must satisfy. This means that we’re not given enough information to determine exactly what $f'(x)$ is; we can determine it only up to a constant $C$. That’s okay! You can still integrate what you’ve got for $f'(x)$….
