Short Answer

Expert verified

Isn鈥檛 mapping another representation of a set of ordered pairs?

Step by step solution

01

Step 1. Given.

A classmate graphed a set of ordered pairs and used the vertical line test to determine whether it was a function.

02

Step 2. To determine.

We have to write a question to help her decide if the same strategy can be applied to mapping.

03

Step 3. Calculation.

We know that mapping is another representation of a set of ordered pairs.

If the vertical line test works, then we can have only one y value for each x value. So we can check if the mapping is one to one, to check if it is a function.

So, we can ask a question like:

Isn鈥檛 mapping another representation of a set of ordered pairs?
