# Math Help - How do you solve this problem?

1. ## 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?

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.

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