Function Tables Practice

A function table is a chart that shows how each input (x-value) is related to an output (y-value) through a specific function or rule.

This function rule indicates that for every input x, the output y is 10 less than x.

The output is 3, because 9 ÷ 3 = 3.

The output is 20, because 5 * 4 = 20.

A table represents a function if each input corresponds to exactly one output.

Input is the value you put into a function, while output is the value you get out after applying the function rule.

The output is 12, because 4 * 3 = 12.

A mapping represents a function if each element in the domain (input) is paired with exactly one element in the range (output).

The output is 6, because 2 * 3 = 6.

The output is -4, because 10 - 14 = -4.
