ANSWER
The input values can be any value that works in the function
Step-by-step explanation
An input-output table is a table made up of rows and columns that displays the inputs of a function along with the corresponding output for each input.
The input values do not have to be consecutive and the output values do not have to be whole numbers.
Depending on the function/relation being described by the table, the output values can be decreasing or increasing as they progress down the table.
However, input values can be any number that will cause the function/relation to work.
Therefore, the correct option is the input values can be any value that works in the function.
