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 between two sets of numbers in which each input value (or member of the domain) is assigned to exactly one output value (or member of the range). It is a rule that associates each input value with a unique output value.
The given table shows a function because each day of the week is associated with a specific number of children in the car. For example, on Sunday, we see that the number of children in the car is not specified. On Monday, we see that the number of children in the car is 2. Similarly, for each day of the week listed in the table, there is a unique corresponding number of children in the car. This one-to-one mapping between the days of the week and the number of children in the car fulfills the criteria for a function.
