Did you make a sketch?
Find the domain and range of: .
We have: .
You should know the graph of: .
. . It is a with its vertex at the origin.
The graph of: . .is the previous graph moved 2 units to the right.
The graph of: . .is the previous graph
. . reflected over the -axis and is "steeper".
Hence, the graph of looks like this:Code:| | 2 - - - + - * - - - - | / \ | / \ |/ \ / \ /| \ |
