Ordered pair{(−6,−1),(−8,4),(−5,4),(3,−9)} from the given set of ordered pairs represents the function.
As given in the question,
Given set of ordered pairs following is the one which represents the function :
- {(−1,−3),(0,−7),(3,3),(3,−4)}
In the given set of ordered pair for input value 3 there are two outputs 3 and -4 , therefore it is not a function.
- {(7,9),(−5,7),(−5,8),(4,−4)}
In the given set of ordered pair for input value -5 there are two outputs 7 and 8 , therefore it is not a function.
- {(−6,−1),(−8,4),(−5,4),(3,−9)}
In the given set of ordered pair each input has unique single output. Therefore it is a function.
- {(−1,0),(−1,−4),(8,−3),(−4,−6)}
In the given set of ordered pair for input value -1 there are two outputs 0 and -4 , therefore it is not a function.
Therefore, ordered pair{(−6,−1),(−8,4),(−5,4),(3,−9)} from the given set of ordered pairs represents the function.
