If the representation is a graph then use the vertical line test. Draw or imagine straight vertical lines going down the graph. If the vertical line only goes through the function line one time then it is a function. For an example, a circle on a coordinate plane is not a function but a wavy line is.
If the representation is a table with points then look at the x values. If x repeats then it is not a function.

Answer:
Mason has
- 16 20¢ stamps;
- 25 3¢ stamps;
- 40 49¢ stamps.
Step-by-step explanation:
Let x be the number of 20¢ stamps, then the number of 3¢ stamps is x + 9.
Mason has 56 total 49¢ and 20¢ stamps, then the number of 49¢ stamps is 56 - x.
Amounts:
- in 49¢:
cents; - in 20¢:
cents; - in 3¢:
cents.
Total amount:

- $23.55.
Hence,

Mason has
- 16 20¢ stamps;
- 25 3¢ stamps;
- 40 49¢ stamps.
