    How do you solve this problem?

    Number one here:

    I got parts a) and b), but I can't get c) or d). How do you do those parts?

    http://www.math.rutgers.edu/~greenfi...dfstuff/w1.pdf

    I think for c), you could take an x value on A and plug it into C(x) to get points on C, but for instance, if put x=1, then C(x)=A(5), but A(5) is not in the domain of A....so this part confuses me. For d), I know we are looking for the inver, which is the reflection about y=x, but I am not sure how to draw that with this graph and what the domain and range would be.

    I'm not really sure whether this is trying to imply the domain is -3<x<2, or just  x \in \mathbb{R}.
    Or even x \in \{-3,0,1,2\}
