This problem says consider the following graph of a function and we're asked to find the domain and the range in interval notation.
00:08
And first for the domain, the domain is a list or a set of all possible x values that are being used in our function.
00:15
And the way we determine our range in interval notation is by first figuring out the lowest x value or the smallest x value that's being used in our function.
00:23
And the lowest x value we see being used is located at this first point on the left that has the point negative seven, negative one.
00:31
And what we're concerned with is the x value at that point, because that's the lowest point we see being used on this function.
00:36
So that starts our domain.
00:39
And since that's a filled in point, which means it is being used in our function, we use a bracket to show that that value is included.
00:46
And then we use every x value from negative seven on this graph, up until we reach this last furthest point to the right.
00:54
And that point is located at five, negative four.
00:59
And again, the only thing we're concerned with is the x value...
