Question

Which of the relations given by the following sets of ordered pairs is a function?O {(2, -7), (6, 5), (-3, 9), (2, 0), (-5,3)}O {(2, 1), (7,5), (-4, 0), (3, 1), (0, -6)}O{(1, 2), (2, 3), (3, 4), (3, 3), (2, 2), (1, 1)}O {(1, 1), (1, 3), (1, 5), (1, 7), (1,9)}

Answer 1

Given:

Given a order sets.

{(2, -7), (6, 5), (-3, 9), (2, 0), (-5,3)}

O {(2, 1), (7,5), (-4, 0), (3, 1), (0, -6)}

O

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

O {(1, 1), (1, 3), (1,5), (1,7),(1,9)}

Required:

To check whether the given sets is function or not.

Step-by-step explanation:

Here the set {(2, -7), (6, 5), (-3, 9), (2, 0), (-5,3)} is not a function.

Because 2 is mapped to two elements.

{(2, 1), (7,5), (-4, 0), (3, 1), (0, -6)} is a function.

{(1, 2), (2, 3), (3, 4), (3, 3), (2, 2), (1, 1)} : Not a function.

{(1, 1), (1, 3), (1, 5), (1, 7), (1,9)} : Not a function.

Final Answer:

The set {(2, 1), (7,5), (-4, 0), (3, 1), (0, -6)} is a function.
