Math Problem Statement

What are the domain and range of this relation? (based on the graph provided)

Solution

To determine the domain and range of the given relation from the graph:

Step 1: Identify the Domain

The domain consists of all the x-values (horizontal axis) corresponding to the points plotted on the graph. From the graph, the points have the following x-values:

  • Point at (-1, -5): x = -1
  • Point at (0, 2): x = 0
  • Point at (4, 5): x = 4

Thus, the domain is: {-1, 0, 4}


Step 2: Identify the Range

The range consists of all the y-values (vertical axis) corresponding to the points plotted on the graph. From the graph, the points have the following y-values:

  • Point at (-1, -5): y = -5
  • Point at (0, 2): y = 2
  • Point at (4, 5): y = 5

Thus, the range is: {-5, 2, 5}


Final Answer:

  • Domain: {-1, 0, 4}
  • Range: {-5, 2, 5}

The correct choice from the options is: Domain: {-1, 0, 4}, Range: {-5, 2, 5}
