Answer:

C.

Step-by-step explanation:

there is no repeated x or y values

hope this helps :)

Answer 2

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.

$\{(-1,5),(0,-3),(2,7)(4,0),(7,5)\}$

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.
