Question

which of the following represents a relation that is not a function? a. x -8 -6 7 10 y 33 31 39 33 b. x -8 -6 0 3 y 33 31 39 33 c. x -8 -6 -8 3 y 33 31 39 33 d. x 7 -6 10 -8 y 33 31 39 33

Answer 1

x => -8 -6 -8 3
y => 33 31 39 33
is not a function because the x value -8 results to two different y-values 33 and 39.
