Answer:
domain: -1 ≤ x ≤ 1
range: -1 ≤ y ≤ 1
Explanation:
Domain
Here we look for the range of x values this graph represents. we can see that is goes from -1 to 1, that's is our domain!
Range
Here we look for the range of y values this graph represents. Again we see that it represents all y values from -1 to 1. That is our range!
