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 relation where each input has a unique output. In other words, for every input, there is only one output.
This table shows a function because each day of the week (input) corresponds to a unique number of children in the car (output). For example, on Sunday there are 2 children in the car, and on Monday there are 4 children in the car. There are no repeated inputs with different outputs, which satisfies the definition of a function.
