Input and Output of a Function

Answer 1

I can’t tell which choice is correct without seeing the table. The inputs of a function are the domain values (the x-values or the first column of the table).

If you paste the table (or list the ordered pairs), I’ll pick the correct option.

Tip: list every distinct first-coordinate shown in the table — that list is the inputs.
