Describe the meaning of the word function in math. Then consider the table. Why does this table show a function?
(2 points)
In math, a function is a relationship between a set of inputs (called the domain) and a set of outputs (called the range), such that each input is related to exactly one output.
In the given table, the day of the week serves as the input (domain) and the number of children in the car serves as the output (range). The table shows a function because each day of the week has a unique corresponding number of children in the car. For example, on Sunday, there are 2 children in the car, and on Monday, there are 4 children in the car. There is no repetition or ambiguity in the output, and each input has exactly one output. Therefore, the table represents a function.
