If you know the function, you can graph it like this: So, let's say the x values are 0, 1, and 2. Lets say the function is y=x+1 So, your outputs would be 1, 2, and 3. Once you're finished with that, you can create the ordered pairs like so: (0,1), (1,2), (2,3) Those would be the ordered pairs. Hope this helps! :)
