I'm a big fan of this computer algebra system.
00:03
I will point out, though, that you could use a graphing calculator that has a y -equals button, and you just might need to find a few of the keys that will get you to the fifth power, move your arrow over.
00:19
You know, might need to find your plus sign 3x through the fourth minus 4x cubed.
00:30
And sometimes it's just faster just to...
00:32
Use the keyboard minus 11x squared plus 3x plus 5.
00:45
And what i like about this calculator is that you can just quickly zoom out and you can just move your screen around.
00:55
Because with some graph and calculators, you have to hit several buttons.
00:59
Like if i hit the graph settings and i don't want my x -axis to be so wide, like maybe i only want to go from negative 3 to 5 that i can do.
01:09
That.
01:09
But with some graph and calculators, there's a lot of work to do.
01:12
So this graph does go infinitely up into the left as well as infinitely up into the right.
01:17
But then you can find some key features, like where the zeros are, we call those roots or x intercepts.
01:29
Let's see, i must be missing something because i only see four roots.
01:36
I'm supposed to have five of them.
01:38
So let me move my, actually, let's just zoom out...
