[Integration] How did they solve this problem?
The first image is the problem and the answer key, and the second image is my work. As you can see, I tried solving it by using the equations of the pieces for the piecewise function and taking the integrals of those but doing this gave me an answer that wasn’t even an option. What did I do wrong here and what should I do instead?
