Question

14.
Odenking, on a recent test, students had to
determine whether the relation represented by the ordered pairs
(1, 2), (6, 12), (12, 24), (18, 36) is a function. Bobby drew the arrow
diagram on the right and said the relation was not a function.
What error did Bobby most likely make?
1
12
18
L2
6
24
36

Answer 1

Bobby's error could be that he took the two 12's that appears on both sides of the mapping as x-values

The ordered pairs are given as:

(x,y) = (1, 2), (6, 12), (12, 24), (18, 36)

When represented using arrows, we have:

1 ---- 2

6 --- 12

12 --- 24

18 --- 36

The above mapping of the relation is a function.

This is so because, all x-values point to exactly one y-value

Bobby's error could be that he took the two 12's that appears on both sides of the mapping as x-values
