The inverse relation is formed from f = {(-2, 1), (0, 3), (3, 4)} by switching x and y. Determine whether the inverse relation is a function.
A
It is a function only if the original inputs and outputs are equal.
B
It is not a function because switching coordinates reverses the order.
C
It is not a function because f has a negative input.
D
It is a function because the original outputs 1, 3, and 4 are all distinct.
