So for this question, we're going to have to figure out the graph for x cubed minus x.
00:06
So we can rewrite this as x times x squared minus 1, which is also same as x times x plus 1 times x minus 1.
00:22
So we know that whenever x equals the 0, negative 1, or 1, it's going to make the y equals 0.
00:32
So we have some graph looking like 0, 1, negative 1, and you're going to just have to plug in the value from now on.
00:48
So it's going to be 0, 0, and 0.
00:53
And we need to find out the value in between 0 and 1 to see if it's negative of positive.
00:58
So if you're plugging x equals 1⁄2, that will be, which is equals to negative, 3 over 8, which will be around here...
