In math, 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.
The table given shows a function because each day of the week is a unique input (domain) and it corresponds to a specific number of children in the car, which is the output (range). Each input (day of the week) is related to exactly one output (number of children in the car), making it a function. There are no repeated inputs in the table, and each input has a unique output, which satisfies the definition of a function in math.
use the table to answer the question.
Day of the week, Number of children in the car
sunday, 2
monday, 4
Tuesday, 4
Wednesday, 3
thursday, 4
friday, 3
