Determine whether the set of ordered pairs $\{ ( 0 , - 1 ) , ( 8,8 ) , ( 1 , - 8 ) , ( 9,0 ) , ( 1,1 ) \}$ represents a function from A to B , where $A = \{ 0,1,8,9 \}$ and $B = \{ - 8 , - 1,0,1,8 \}$
A)a function from A to B
B)not a function from A to B

Question

Quizplus · Accepted Answer

The set of ordered pairs does not represent a function from A to B because the element 1 in set A is associated with two different elements (-8 and 1) in set B. A function cannot have two different outputs for the same input.

Determine Whether the Set of Ordered Pairs {(0,−1),(8,8),(1,−8),(9,0),(1,1)}\{ ( 0 , - 1 ) , ( 8,8 ) , ( 1 , - 8 ) , ( 9,0 ) , ( 1,1 ) \}{(0,−1),(8,8),(1,−8),(9,0),(1,1)}
