This problem, we're going to be doing a fourth degree polynomial.
00:03
We have a negative leading coefficient, and there's three x intercepts.
00:07
Let's start by doing our sketch.
00:09
So here's our x and our y axis.
00:11
When we go about doing our problem here, if there's only three x intercepts, that means one of them has to be a double root.
00:18
Also, the fact that it is negative leading coefficient and even, that means that the ends are going to have to go in a down -down position.
00:25
So what we're going to do then is go ahead and have it go up, followed by down, and then we're going to want to bounce.
00:34
We could bounce in the beginning or we can bounce at the end.
00:36
It doesn't really matter.
00:37
So we're going to come up.
00:39
We're going to come back down...
