Question 1128872


The function f = {(1,2),(2,3),(3,3)} is one to one because every x value is different. The x values are given to be 1, 2, and 3. 

 
The function g = {(1,0)(2,3),(3,2),(4,8)} is also one to one because every x value is different. The x values are given to be 1, 2, 3, and 4.

Both relations are one to one functions.
