Hello there. To solve this question, we'll have to determine the domain of the function given the ordered pairs.
Given an ordered pair (x, y), we can rearrage them in the following diagram:
In the left bubble, we input the x-coordinates of the ordered pairs, while in the right bubble, the y-coordinates.
We can also connect the points with their corresponding pair.
The arrows in yellow are the function, taking values from the domain to the image set.
Therefore, the left bubble contains the values of the domain of the function. We rewrite it in set notation as:
This is the answer to this question.
