In math, a function is a relationship between a set of inputs (independent variable) and a set of outputs (dependent variable) where each input is related to exactly one output.
This table shows a function because each day of the week (input) is associated with a specific number of children in the car (output). For example, Sunday is associated with 2 children in the car, Monday with 4 children, and so on. Each day corresponds to exactly one number of children in the car, satisfying the definition of a function.
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
Saturday 0
