We want to graph the equation, y equals x squared minus 2.
00:04
We're going to let x equals negative 3, negative 2, negative 1, 0, 1, 2, and 3, just to give us a good idea of the whole behavior of the graph.
00:17
So when we plug in negative 3, that is a different color here, negative 3 gets squared minus 2, which is 9 minus 2, so 7.
00:26
Negative 2 squared minus 2 is 4 minus 2 which is 2.
00:32
Negative 1 squared minus 2 is 1 minus 2 so negative 1.
00:38
0 squared minus 2 is 0 minus 2 so negative 2 1 squared minus 2 equals 1 minus 2 which is negative 1 again.
00:48
You'll see that we have some repetition throughout this graph.
00:52
Those are all my y values.

So this table represents a set of points...
