{(7,1),(7,−7),(−8,3),(9,5)}
The set of ordered pairs that does not represent a function is:
{
(-1, -3),
(2, -5),
(-2, 0),
(6, -3)
}
The set of ordered pairs that does not represent a function is:
{(7,1),(7,−7),(−8,3),(9,5)}
To determine which set of ordered pairs does not represent a function, we need to check if there are any repeated x-values.
Let's go through each set of ordered pairs:
1. {(5,-3), (1,-1), (-1,8), (9,-1)} - There are no repeated x-values in this set, so it represents a function.
2. {(-1,-3), (2,-5), (-2,0), (6,-3)} - There are no repeated x-values in this set, so it represents a function.
3. {(-7,-3), (-6,4), (-2,-5), (0,-3)} - There are no repeated x-values in this set, so it represents a function.
4. {(7,1), (7,-7), (-8,3), (9,5)} - The x-value 7 is repeated in this set. Therefore, this set does not represent a function.
Therefore, the correct answer is:
{(7,1), (7,-7), (-8,3), (9,5)}
