So in this problem, you are asked to graph the inverse function if you're given the function shown in the graph.
00:11
So a couple of things that you need to know about inverse functions.
00:15
First, they are symmetric with respect to the line y equals x.
00:20
So there's your line y equals x.
00:24
So a symmetric line means that you have to be able to fold over that line, just like you would if you were doing like an art.
00:32
Project with symmetry and you splatter paint on one half and you fold the paper over, it's going to match up on the other side.
00:41
All right.
00:41
So then the next thing that's going to help us graph the inverse function is that if the point a -b is on the function, then we just switch the order and b -a is on the inverse.
00:57
All right, so let's write down the ordered pair that we have on the function.
01:01
We have the point for one on the function, and we also have the point negative 4, negative 4 on the function...
