In mathematics, a function is a relation between a set of inputs (the domain) and a set of possible outputs (the range), where each input is related to exactly one output. This means that for each input, there is only one corresponding output.
In the table provided, each day of the week is paired with a specific number of children in the car. For each day of the week, there is only one corresponding number of children in the car. For example, Sunday is always associated with 2 children in the car, Monday with 4, Tuesday with 4, and so on.
Because each input (day of the week) is related to only one output (number of children in the car) and there are no repetitions or multiple outputs for the same input, this table shows a function.
use the table to answer the question.
day of the week: sunday, monday, tuseday, wednesday, thursday, friday, saturday
number of children in the car: 2, 4, 4, 3, 4, 3, 0
