Question

Which set of ordered pairs does not represent a function

Answer 1

Second one.

The first set of ordered pairs is a function, because no two ordered pairs have the same first coordinates with different second coordinates. The second example is not a function, because it contains the ordered pairs (1,2) and (1,5).

Answer 2

Answer:

The Second one {(-8,-7), (4,-2), (2,9), (-8,8)}

Step-by-step explanation:

A function only gives ONE out put for a given value. But the second set has two outputs if we input -8, it gives you -7 and 8 so this must not be a function.
