Graph each function and approximate any local maxima or minima to the nearest tenth.
1. P(x) = 2x^3  5x
2. P(x) = 2x^3  4x + 1

drwls,
We can't draw graphs for you here. You will have to get some graph paper and draw your own. It will be good practice for you.
The first equation has a local maximum or minimum at x = + or  sqrt(5/6)
The second funtion has a local maximum or minimum at x = + or  sqrt(2/3)
When you draw the curves you will see which are maxima or minima. Both have one of each.
