Describe the meaning of the word function in math. Then consider the table. Why does this table show a function?
In math, a function is a relationship or correspondence between two sets where each input value from one set corresponds to exactly one output value in the other set. In this table, the "Day of the Week" serves as the input set, and the "Number of Children in the Car" serves as the output set.
This table shows a function because each day of the week corresponds to exactly one number of children in the car. For example, on Sunday there are 2 children in the car, on Monday there are 4 children, and so on. Each day has a unique corresponding number of children in the car, meeting the requirements of a mathematical function.
