In this question, we are going to look at the given graph and identify the domain and range using interval notation.
00:11
For domain, you look at x values.
00:19
And on this graph, on the first piece of the graph, it starts at an x value of negative 1.
00:29
It has an open circle.
00:34
And i'm just plotting the x values on the x axis.
00:38
And that piece of the function continues until 2, where there's another open circle.
00:50
So those are the x values represented on the first piece of the function, and then again from 3 to 4, where there are closed circles on each end of the piece.
01:12
So the domain represented on the x -axis here has two intervals.
01:19
Negative 1 with a parentheses to 2, parentheses because of the open circles, union symbol 3 to 4 with brackets because of the closed points...
