It's important to know that empty circles refer to open intervals or parenthesis.
In this case, we observe that the first interval of the domain is (-1, 1) and the second interval of the domain is (2, 5), so the whole domain would be the union of these two intervals.
To obtain the range, let's observe the y-values. The function goes from y = -5 to y = 3, so the range would be
