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

{(-6,-6), (-2,-2), (7,-6), (-5,0)}

Step-by-step explanation:

Function: Every domain (x-value) has only one range (y-value)

The other choices had an x-value that had more than one y-value, which makes only this one a function.

Hope this helped :)

the correct answer is b. negative exponential growth.

step-by-step explanation:

you can tell it's an exponential function because it decreases rapidly then levels out and never touches the x-axis.

it is negative because the y-axis decreases as the x-axis increases.

therefore it is a negative exponential growth graph.
