Question

Which relation represents the information in the graph?

Answer 1

5. OPTION B.

6. OPTION J

Explanation:

By definition:

- The Domain is the the set of all the input values. This is the set of all the x-coordinates (remember that the x-coordinate is the first number in each pair).

- The Range is the set of all output values, which is the set of all the y-coordinates ( Remember that the y-coordinate is the second number in each pair).

5. Observe the graph and write the coordinates of each point. These are:

`(1,5)\\(2,6)\\(3,10)\\(4,15)`

Then, the relation shown in the graph is:

`\{(1,5),(2,6),(3,10),(4,15)\}`

6. Based on the definition shown before, you can determine that the range of the relation shown in the graph is:

`\{5,6,10,15\}`
