Question

This table displays a scenario.

A two column table with seven rows. The first column, gallons, g, has the entries, 1, 2, 3, 4, 5, 6. The second column, liters, l, has the entries, 3.79, 7.58, 11.37, 15.16, 18.95, 22.74.
What can be determined from the table? Check all that apply.

The independent variable is the number of gallons.
Liters is a function of Gallons.
The equation l = 3.79g represents the table.
As the number of gallons increases, the number of liters increases.
This is a function because every input has exactly one output.

Answer 1

All five statements are true.

- The independent variable is gallons (g), since liters depend on the number of gallons.
- Liters is a function of gallons (each g gives one l).
- l = 3.79g matches every row (3.79·1 = 3.79, 3.79·2 = 7.58, …).
- As gallons increase, liters increase (the values rise).
- It is a function because each input (each g value) has exactly one output (one l value).
