A function in math is a rule that pairs each input with exactly one output. The input is usually called the independent variable and the output is the dependent variable.
In the table:
- The inputs are the days of the week (Sunday, Monday, …).
- The outputs are the number of children in the car for each day.
This table shows a function because each day (each input) is matched with exactly one number (one output). Even though the same number (like 4) appears for different days, that’s okay — a function only forbids one input having two different outputs. For example, Tuesday → 4 and Wednesday → 3, and Saturday → 0, so every day has one clear number. Thus the relation in the table is a function.
