Final answer:
The given relation represents a function as each input value is paired with the same output value of 7.
Step-by-step explanation:
To determine if the given relation represents a function, we need to check if each input value (x-coordinate) is paired with a unique output value (y-coordinate).
In this case, the relation is:
- a. (-1,7)
- b. (-7,7)
- c. (17,7)
- d. (11,7)
Since each x-coordinate is paired with the same y-coordinate (7), the relation represents a function. In this function, every input value maps to the output value of 7.
