Respuesta :

We have the following relation provided:

[tex]S=\left\lbrace (-9,0),(-4,5),(0,9),(4,5)\right\rbrace [/tex]

And we want to determine if is a function or not: For this case we need to verify if each input value (x)  have only one output value.

For x=-9 y=0

For x=-4, y=5

For x=0, y=9

For x=4, y=5

Since each value of x have NOT an only one y value we can conclude that we have a function.
