What we saw an example 2a in the book is that they took f of x equals x to the fourth.
00:08
They first did an x -axis reflection, and then after that they followed it by shifting it up to.
00:14
So we're going to reverse those.
00:16
So we're going to start with f of x equals x to the fourth, just a rough sketch.
00:19
It looks kind of like this.
00:22
And next we're going to shift it up to, and then we're going to reflect it across the x -axis.
00:31
And that does not look like the other one.
00:35
The order of transformations does matter.
00:40
We can see that algebraically if we think about what the equation would be for the transformed function.
00:47
So we would have f of x equals x to the fourth plus two for shifting up to and then we would multiply that by a negative for the x -axis reflection.
01:00
And because we would have to distribute that negative, it looks different...
