Answer: inverse functions
Step-by-step explanation:
Inverse functions are symmetrical about the y=x axis. You could dot that line in by plotting points like (-4,-4) (-3,-3) (-1,-1) (0,0) (1,1) (3,3) etc. Then since you could fold the graph on that dotted axis and the two lines match up, you know they are inverses of each other.
