Question

{( -8,8), (-8,2), (-8,4), (-5,6), (- 9,3), (-4,9)}

Does the relation represent a function?
O No
o Yes

Answer 1

No. Functions must pass the vertical line test. 3 of the coordinates have -8 as the x value, meaning that there are 3 different outputs to the same input. This does not pass the vertical line test.
