I guess we need to start by solving for k. To do that, we need to set the integral of f(x) from 0 to 2 equal to 1, right? Please correct me if I'm wrong. Anyways, what I'm really confused about is the second part. I just cant figure out how to go about finding 2 random values...

Thanks in advance if anyone can help!
