Here we're given four different transformations, and we want to determine which ones would not return the shape to its original position.
00:08
So let's look at each of these individually and see which ones will return their shape to their original position.
00:14
So let's start with number one, three units up, three units down.
00:19
So let's try this on a graph.
00:21
So let's say we have a parabola.
00:24
I shift it three units up and then three units down again.
00:34
So that's going to put us back on our original parabola.
00:41
So we know that 1 is not our answer because it does return to our original position.
00:49
So now let's take a look at 2.
00:52
We want to reflect over line p, then reflect over line p again.
00:57
So let's draw this.
00:58
So let's say i have my parabola again and i reflect about the x axis.
01:04
And then i reflect about the x -axis again.
01:10
That's going to put me back where i started.
01:13
So this one is also not our answer because we will return our shape to the original position.
01:22
So next we have one unit right, four units left, and three units right...
