Question

Which set of ordered pairs does not represent a function? O {(-3,-9), (7,9), (9, 1), (7,3)} O {(-3,8),(-6,5), (-5, -6), (1,-6)} O {(3,1),(-2,-9), (6,-9),(4,6)} o {(4,3), (-4,4),(-2,-5), (6,4)}​

Answer 1

Answer:

The first set of ordered pairs is not a function.

Step-by-step explanation:

The X value of 7 repeats, which means that it is not a function

Answer 2

Second, third and fourth set of ordered pairs does not represent a function so only the first one is a function.
This is because each x value has to has their distinct y value. So you notice all sets of ordered pairs except the first one, two different x-values have the common y-value, which cannot be happen.
