Question

Write the domain and range of g as intervals or unions of intervals

Answer 1

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.

`\text{Domain}=(-1,1)\cup(2,5)`

To obtain the range, let's observe the y-values. The function goes from y = -5 to y = 3, so the range would be

`Range=(-5,3)`
