So suppose i want to find the domain of a graph.
00:03
What exactly is the definition of domain? well, domain is all my x values or my inputs in the graph.
00:09
Okay, so x values, i'm thinking about left to right.
00:12
What's my leftmost point versus my rightmost point? looking on my x axis, what's my leftmost point? well, my left most point happens at the x value in negative 2.
00:20
I hit all the values between negative 2, and then i stop at my rightmost point, which is an open circle to 1.
00:28
Okay, so my leftmost point is negative 2.
00:31
Close circle, so that means a square bracket.
00:33
I hit negative 2 in my domain all the way until i hit 1.
00:37
I get really close to 1, but don't touch it...
