DETERMINE WHETHER EACH SET OF ORDERED PAIRS IS A FUNCTION WORKSHEET

Which of the following set of ordered pairs are functions ? Give reasons.

Problem 1 :

{(1, 3), (2, 4), (3, 5), (4, 6)}

Solution

Problem 2 :

{(1, 3), (3, 2), (1, 7), (-1, 4)}

Solution

Problem 3 :

{(2, -1), (2, 0), (2, 3), (2, 11)}

Solution

Problem 4 :

{(7, 6), (5, 6), (3, 6), (-4, 6)}

Solution

Problem 5 :

{(0, 0), (1, 0), (3, 0), (5, 0)}

Solution

Problem 6 :

{(0, 0), (0, -2), (0, 2), (0, 4)}

Solution

Tell whether the relation is a function. Explain.

Problem 1 :

 (3, -2), (0, 1), (1, 0), (-2, -1), (2, -1)

Solution

Problem 2 :

(2, -5), (-2, 5), (-1, 4), (-2, 0), (3, -4)

Solution

Problem 3 :

(0, 1), (1, 0), (2, 3), (3, 2), (4, 4)

Solution

Problem 4 :

(-1, -1), (2, 5), (4, 8), (-5, -9), (-1, -5)

Solution

Problem 5 :

The relation given by the ordered pairs (-6, 3), (-2, 4), (1, 5), and (4, 0) is a function. Which ordered pair can be included with this relation to form a new relation that is also a function?

A. (1, -5)       B. (6, 3)      C. (-2, 19)      D. (4, 4)
