Does this set of ordered pairs represent a function? Why or why not ?
2 answers:
Answer:
C. Yes, because every x-value corresponds to exactly one y-value
Step-by-step explanation:
We are asked to find whether the given ordered pairs represent a function or not.
We know that a relation is a function, when each input of x value gives exactly one output of y-value.
In a function two or more x-coordinates can give same y-value, but one x-value cannot give two y-values.
We can see that in our given set each x-value corresponds to exactly one y-value, therefore, the given set represents a function.
