Math Problem Statement

Use the graph of the relation to list ordered pairs, find the domain and the range.

Solution

Let's analyze the graph and answer each part of the problem:

(a) List the ordered pairs of the relation:

To find the ordered pairs, we take the coordinates of each point from the graph.

  1. The first point is located at (-4, 5).
  2. The second point is at (-2, -2).
  3. The third point is at (2, 3).
  4. The fourth point is at (5, -3).
  5. The fifth point is at (7, 1).

Now, we order the points by increasing values of xx, and if xx values are equal, we order by increasing yy.

The ordered pairs are: (4,5),(2,2),(2,3),(5,3),(7,1)(-4, 5), (-2, -2), (2, 3), (5, -3), (7, 1)

(b) Find the domain of the relation:

The domain is the set of all possible xx-values in the relation. From the ordered pairs, the xx-values are: 4,2,2,5,7-4, -2, 2, 5, 7 Thus, the domain is: {4,2,2,5,7}\{-4, -2, 2, 5, 7\}

(c) Find the range of the relation:

The range is the set of all possible yy-values in the relation. From the ordered pairs, the yy-values are: 5,2,3,3,15, -2, 3, -3, 1 Thus, the range is: {5,2,3,3,1}\{5, -2, 3, -3, 1\}


Would you like further clarification or details on any of these points?

Relative questions:

  1. What would change if a new point was added with an xx-coordinate of 11?
  2. How can you determine if this relation is a function?
  3. If the graph were extended, how would you predict new points for the relation?
  4. Can a relation have multiple points with the same yy-coordinate but different xx-coordinates?
  5. What is the impact of reflecting the graph across the xx-axis?

Tip:

When finding the domain and range of a graph, always look for all unique xx-values for the domain and all unique yy-values for the range!
