The set of x and y coordinates representing a relation that is not a function is: C. (0, 0), (1, 1), (1, -1), (2, 4), (2, -4)
Recall:
- For a relationship between x and y values to be defined as a function, every x-value must have only one possible y-value that corresponds or is related to it.
The set of relation of x and y coordinate pairs in A, B, and D all have exactly one y-value assigned to every x-value.
In set C, the relation has two different y-values, -1 and 1, assigned to one x-value, 1.
This makes set C not a function.
In conclusion, the set of x and y coordinates representing a relation that is not a function is: C. (0, 0), (1, 1), (1, -1), (2, 4), (2, -4)
