## Which is which - College Algebra

• 0:01 - 0:06
This first graph over here, this green one, is the graph of y equals x to the
• 0:06 - 0:10
5th. And this purple one is y equals x to the 6th. Notice that this does, in
• 0:10 - 0:14
fact, continue that pattern that we had started to pick up on over here. Just
• 0:14 - 0:19
like x squared and x to the 4th, x to the 6this shaped sort of like a U.
• 0:19 - 0:25
Although it's even steeper or skinnier, than the x to the 4th function. And it's
• 0:25 - 0:30
base looks to be a bit wider. So, as you move away from 0, the graph isn't
• 0:30 - 0:34
initially increasing very quickly. And then it shoots up really fast as soon as
• 0:34 - 0:39
we move past 1. Think about why this is y. You might want to make a T chart with
• 0:39 - 0:44
values at the input for the function smaller than 1, and see how the value of y
• 0:44 - 0:49
increases as x increases. Now, just like y equals x to the 3rd, y equals x to
• 0:49 - 0:54
the 5th has one tail, or one end of the graph pointing to negative infinity, and
• 0:54 - 0:58
the other pointing to positive infinity. Then we can see that y equals x to the
• 0:58 - 1:03
5th is, once again, a skinnier graph than y equals x to the 3rd. But it still
• 1:03 - 1:06
has pretty much the same shape. This is really interesting.
