Question

The manager of Extreme Video Games keeps track of the profits the company earned after releasing one of its latest games. During the first week, the game profits were $15,000. In the second week, the profits grew to $22,500. In the third week, profits held steady at $22,500, and in the fourth week, profits grew to $25,000. Using x to represent the week and y to represent the profits earned, create a mapping diagram to represent this relation.

Answer 1

See the diagram attached.

Explanation:

First, we put the data into a table format as follows:

week (x) profits (y)

1 $15,000

2 $22,500

3 $22,500

4 $25,000

Now it is easy to see which x-value in the domain is related to each y-value on the range. Notice that two x-values (or inputs) have the same y-value (or output).
