Which of the following values could be used for x and would cause the following relation to NOT be a function?

Question

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

A. x=-4
B. x=3
C. x=0
D. x=6

Answer 1

The relation {(2,3), (-2,6), (3,-4), (x, 2), (5,-9)} is a function if each x-value is paired with only one y-value.

In this case, each x-value is paired with a unique y-value except for the x-value of 3.

When x = 3, we have two y-values: y = -4 and y = 2.

Therefore, the value of x that would cause the relation to NOT be a function is x = 3.

Therefore, the correct answer is B. x = 3.
