Quizplus · Accepted Answer

A function is one-to-one if each input has a unique output and no output is repeated for different inputs. In the given set, all inputs (first elements of the ordered pairs) and outputs (second elements of the ordered pairs) are unique, thus the function is one-to-one.

Determine Whether or Not the Function Is One-To-One {(6,−5),(8,−15),(11,−10),(19,−19),(22,−23)}\{ ( 6 , - 5 ) , ( 8 , - 15 ) , ( 11 , - 10 ) , ( 19 , - 19 ) , ( 22 , - 23 ) \}{(6,−5),(8,−15),(11,−10),(19,−19),(22,−23)}

Determine Whether or Not the Function Is One-To-One $\{ ( 6 , - 5 ) , ( 8 , - 15 ) , ( 11 , - 10 ) , ( 19 , - 19 ) , ( 22 , - 23 ) \}$
