00:01 So i have the intervals negative 1 to positive 5 and 0 to 8.
00:12 I want to find first the intersection.
00:15 So i'm going to just graph this.
00:17 My leftmost point is negative 1.
00:21 My rightmost point is 8.
00:32 So my first graph, i'm going to make two number lines so it's a little easier to see.
00:46 So my first graph goes from negative 1, and i'm including that point, to 5...
