Okay, so you have a graph that looks something like this.
00:08
And you need to find the minimum degree of the polynomial.
00:12
So there are one to three turning points, which means at minimum this is a fourth degree polynomial.
00:24
So the degree is always one more than the turning points.
00:30
Determine whether the leading coefficient is negative or positive.
00:36
This is an even degree.
00:41
Even degrees start high and n high.
00:46
So the leading coefficient is positive.
00:51
We can compare this to something we're more familiar with, which is a parabola.
00:56
So this is x squared.
00:57
While if it's upside down, this is not.
01:01
Negative x squared...
