In math, a function is a relationship or rule that assigns each input value from a set to exactly one output value from another set. This means that for every input, there is only one corresponding output.
In the given table, the input values are the days of the week, and the output values are the number of children in the car on each day. Each day of the week is associated with a specific number of children in the car, and there are no repeated input values with different output values. Therefore, this table shows a function because each input (day of the week) is mapped to exactly one output (number of children in the car) as per the definition of a function.
