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, where each element in the first set (called the domain) is paired with exactly one element in the second set (called the range). The table shows a function because each day of the week (the domain) is paired with a specific number of children in the car (the range). There are no repetitions or gaps in the pairs, satisfying the requirement of a function.
