Question

Interpreting a Function
This table displays a scenario.

A 2-column table with 6 rows. Column 1 is labeled Quarts, q with entries 1, 2, 3, 4, 5, 6. Column 2 is labeled Liters, l with entries 0.95, 1.9, 2.85, 3.8, 4.75, 5.7.

What can be determined from the table?
Check all that apply.
The number of quarts is the input, and the number of liters is the output.
The table displays a relationship between liters and quarts.
The equation l = 0.95q represents the table.
There are 0.95 liters in every quart.
This is a function because every input has exactly one output.

Answer 1

All five statements apply.

- The number of quarts is the input, and the number of liters is the output. — True: q is the independent/input column and l the dependent/output column.
- The table displays a relationship between liters and quarts. — True: the table gives l-values corresponding to q-values.
- The equation l = 0.95q represents the table. — True: each l equals 0.95 times q (0.95·1 = 0.95, 0.95·2 = 1.9, etc.).
- There are 0.95 liters in every quart. — True according to the table (1 quart → 0.95 liters).
- This is a function because every input has exactly one output. — True: each q-value maps to a single l-value.
