In mathematics, a function is a relation between a set of inputs and a set of possible outputs with the property that each input is related to exactly one output.
The table in this question shows a function because for each day of the week (input), there is a corresponding number of children in the car (output). Each input is related to exactly one output, and there are no repeated inputs with different outputs. Therefore, this table satisfies the definition of a function.
Day of the Week, Number of Children in the Car
Sunday, 2
Monday, 4
Tuesday, 4
Wednesday, 3
Thursday, 4
Friday, 3
Saturday, 0
