I know you asked this 6 years ago, but someone may learn something from this answer:

You have a peculiar set of inputs and outputs. The first two especially should give you a hint: they're the same! 0 squared is 0; similarly, 1 squared is 1. If you square your other inputs, you'll see they're the same way.

Your fill-in-the-blank sentence is given a hint in the next sentence: a function has only one output for each input, that is, you won't input 3 and get both 6 and 10. So your sentence is "yes, because for each input there is exactly one output."
