So for this question we are given a sixth degree polynomial and we want to use a graphing calculator in order to find the relative maxima.
00:12
So what i did was i went to the graphing calculator on desmos.

I think they are really solid because when you put in the function it'll actually isolate the important features so it will actually give you the points for the maxima, the minima, x -intercepts, y -intercepts, and so on.
00:35
So you can type your function in to one of the options on the left hand side.
00:40
You'll see the graph.
00:41
Look for a little wrench off on the right hand side.
00:45
That will allow you to change the viewing window because there are very large values for the function here.
00:53
So you can see from the previous part to the problem that the best viewing window is from negative 10 to 10 in the y direction and about negative 7 ,000 to 28 ,000 in the y direction.

So once you have all these adjustments you should be able to get the three critical points that give you the maxima...
