Question

Determine whether the relation is a function.

{(-4,1),(0,0),(4,0), (0,4)}​

Answer 1

NOT a function

Explanation:

recall that for a relation to be a function, each value of x must result in only 1 unique value of y.

in this case we can see that for (0,0), when x = 0, y = 0

but the last set of coordinates (0,4), when x = 0, y = 4

because we have the same x = 0 resulting in two different values of y, we can conclude that the relation is NOT a function
