Question

Which set of ordered pairs does not represent a function?

O {(-6,0), (8,0), (5,9), (7,4)}
O {(-6, -2), (3,-7), (5,9), (9, -2)}
O {(9,-2),(-4,-9), (-9,0), (9,7)}
O {(-1,7), (-8,5), (0,0), (7,5)}

Answer 1

A function cannot have the same input with different numbers for outputs

Solution: C is not a function

Answer 2

A function is when an input (x) only has exacty one output (y).

Explanation:

Answer:

O {(9,-2),(-4,-9), (-9,0), (9,7)}

That is not a function because the input {9} is shown more than once.
