Range:

Domain:

#### Explanation:

We can first consider the range, rather simply, we must consider all the values that

Now we can consider the domain, to what we can consider for what values of

graph{x^2-1 [-3.538, 3.572, -1.437, 2.118]}

we can evidently see that where

So hence the domain is;
