Question

Which set of Jrdered pairs represents a function?O{(-8,4), (-5,7), (-8,-1), (-4,8)}O{(-5,-5), (7,2), (-7, -3), (-7,0)}O{(-6,2), (-5,6), (-3,7), (–9, 2)}O{(-7,8), (-7,2), (7,6), (4, 2)}

Answer 1

A function can't have repeated x values with different output values (y-values).

Like:

(-8,4), (-5,7), (-8,-1), (-4,8)

We can see that we have to -8 x values with different output values (-8,4)(-8,-1)

The correct option is:

{(-6,2), (-5,6), (-3,7), (–9, 2)}
