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 relation between a set of inputs (the domain) and a set of outputs (the range) where each input has exactly one output. In other words, for each input, there is only one corresponding output.
Looking at the table provided, each day of the week is a different input, and the number of children in the car is the output. Each day of the week has a specific number of children in the car associated with it, and there are no repeated outputs for any specific input. This table shows a function because each input (day of the week) has exactly one output (number of children in the car), satisfying the definition of a function.
