A) function
domain: $\{ 11,4 , - 5,20 \}$
range: $\{ - 4 , - 3,0,3,5 \}$

B) function
domain: $\{ - 4 , - 3,0,3,5 \}$
range: $\{ 11,4 , - 5,20 \}$

C) not a function

Quizplus · Accepted Answer

A relation is a function if each input (x-value) has exactly one output (y-value). In the given set, each x-value is unique and maps to exactly one y-value, so it is a function. The domain (all x-values) is $\{ - 4 , - 3,0,3,5 \}$, and the range (all y-values) is $\{ 11,4 , - 5,20 \}$.

Determine Whether the Relation Represents a Function {(−4,11),(−3,4),(0,−5),(3,4),(5,20)}\{ ( - 4,11 ) , ( - 3,4 ) , ( 0 , - 5 ) , ( 3,4 ) , ( 5,20 ) \}{(−4,11),(−3,4),(0,−5),(3,4),(5,20)}

Determine Whether the Relation Represents a Function $\{ ( - 4,11 ) , ( - 3,4 ) , ( 0 , - 5 ) , ( 3,4 ) , ( 5,20 ) \}$
