The set of ordered pairs that does not represent a function is {(1,−9),(5,2),(−9,4),(5,−5)}.
The set of ordered pairs that does not represent a function is:
{(1,−9),(5,2),(−9,4),(5,−5)}
To determine which set of ordered pairs does not represent a function, we need to check if each x-value in the set is paired with exactly one y-value.
Let's analyze each set of ordered pairs:
1. {(−6,−4),(−2,−4),(−4,−7),(7,−6)}
- This set represents a function since each x-value is paired with a unique y-value.
2. {(1,−9),(5,2),(−9,4),(5,−5)}
- This set does not represent a function because the x-value 5 is paired with two different y-values (-5 and 2).
3. {(−1,9),(−9,3),(−8,9),(−7,−2)}
- This set represents a function since each x-value is paired with a unique y-value.
4. {(9,−3),(8,0),(−5,−3),(1,2)}
- This set represents a function since each x-value is paired with a unique y-value.
Therefore, the set of ordered pairs that does not represent a function is:
{(1,−9),(5,2),(−9,4),(5,−5)}
