All right.

Hi.

So you've been asked to sketch a graph of this and make sure your graph is all intercept and exhibits proper end behavior.
00:12
Okay, so y equals x plus one times x plus one times x minus two would look like this.
00:19
It would have a y intercept at two because if you make the value, make x zero, i'll make all these x zero.
00:30
That'd be negative one times one.
00:31
Times negative 2, that actually equals 2.
00:33
That's why the y intercept is 2.
00:35
It has 3x intercepts of negative 1, 1, and 2, because if you make x1 here, everything becomes 0.
00:43
If you make x negative 1 here, everything becomes 0.
00:46
And if you make x2 here, everything becomes 0.
00:50
Notice it has a couple of different little vertices, i guess...
