Question 2 • EF Math 12 1st Nine Weeks

Look at the graph of the given relation. Determine whether the relation is a function. Explain why or why not. (4.2, 6.2), (-0.8, 6.2), (-3.8, 4.2), (-3.8, -1.8)

Question illustration
Answer

Answer:

The relation is not a function. The x-value -3.8 is paired with two different y-values, 4.2 and -1.8, so it fails the vertical line test.
