Math Problem Statement
What is the domain of this relation?
Solution
The domain of a relation consists of all the x-coordinates (horizontal values) of the points in the relation. Let's examine the points on the graph:
- The first point is at , so the x-coordinate is .
- The second point is at , so the x-coordinate is .
- The third point is at , so the x-coordinate is .
- The fourth point is at , so the x-coordinate is .
Thus, the domain of this relation is the set of all x-coordinates: .
Looking at the answer choices, the correct domain is .
It appears there is a slight mistake in one option where should have been . Thus, this closest matching answer is .
