Solving Someone's Math Problems

So, a month ago, there is this post by someone, asking me to solve this:

Now, since there was no further explanation, I have made three assumptions: 

 

1. Find f'(x) for some arbitrary value of x.

2. Differentiate f'(x).

3. Integrate f'(x).

 

Naturally, I went for the third option, because the third option was fun. Also, as Problems 1, 2, 3 are easy integration questions, I went to solve Problem 4 first:

And the solution is as thus.

 

Alright, I will admit that I had to search for the answer first before finding out the specific procedure to solve Problem 4, but to my credit, I did find out the general procedure with prior knowledge of integration (as remember: integration is the anti-derivative, so for any f(x) = ∫f'(x)dx, (d/dx) f(x) should be equal to f'(x)). I suspect that with the method I used, there will be cases where trial and error is required.

i second that...but also wonder what context this did have originally...i know renegade said there was no context given but i am curious if it was just someones math homework (high level im guessing) or if it had some deeper meaning...
