We are looking for the coordinates of points in specific quadrants that fit a very specific condition.
00:09
And i am looking for points that if i take the x coordinate and cube that number, it's going to be less than zero.
00:18
And at the same time, if i take the y coordinate and cube it, it will be greater than zero.
00:27
So what does it mean for x cubed to be less than zero? that means it has to be a negative number.
00:35
And in order for this to be a negative number, we would have to have a negative value to cube, and that way it would be less than zero because we have three negative signs.
00:48
And for y cube to be greater than zero, we are looking for a positive y value, so when we cube it, it will stay positive.
00:57
So this is the condition we're looking at.
00:59
If we look at quadrant 1, we have a positive x and a positive y.
01:08
If we cube either of those, they will both stay positive.
01:13
So we cannot use a point out of quadrant 1.
01:16
If you look in quadrant 2, we do have a negative x coordinate...
