Answer:
Any linear function, like f(x) = 3x +2
Step-by-step explanation:
Translating this function to the right 1 unit gives ...
... f(x -1) = 3(x -1) +2 = 3x -1
Translating this function down 3 units gives ...
... f(x) -3 = (3x +2) -3 = 3x -1
You will note that the chosen horizontal translation produces the same result as the chosen vertical translation.
_____
The corresponding translations are related to the slope of the graph. For a linear function, the slope is the same everywhere, so the necessary vertical and horizontal translations that map the function to itself are the same everywhere.
