Which set of ordered pairs represents a function? A. {(9,3),(2,-2),(1,3),(0,-4)}

B.{(-9,-5),(-9,-3),(-7,-9),(-4,9)}< br />
C.{(4,-5),(-2,-3),(6,9),(6,0)}

D.{(-2,-2),(-1,7)(8,6),(8,0)}

B(-9-5)(-9-3)(7-9)(-4-9)

the circle graph is not a function.

step-by-step explanation:

the graph of the circle is not a function.

because for a graph to be a function, each value of x must give one value of y

in the circle, the values of x for -2< x< 2 each give 2 values of y.

hence this is not a function.

x^6

step-by-step explanation:

this is correct because:

x-6=0

0*x=0

so

x^6
