Which statement about an input/output table is true?

the input values must be consecutive numbers.
the output values must be whole numbers.
the input values can be any numbers that work in the function.
the output values will always be increasing down the table.

The answer is c because the input values do not have to be consecutive, the output values can be decimals and fractions, and the output values are not always increasing as they go on, sometimes they decrease. for example, look at exponential decay and exponential growth. hope this helped (;

Hope i can you!
