Answer:

2) y = 0.5^x

Step-by-step explanation:

Plug in x coordinates to see which equation makes up the graph. We can see that the y values lower even after using positive numbers so this eliminates the possibility of 1) as that would make the y values increase. Starting with coordinates (-1, 2), let's plug these into 2):

y = 0.5^x

2 = 0.5^-1

2 = 2

Correct

Use another pair of coordinates to see if it still works:

(-2, 4)

4 = 0.5^-2

4 = 4

It does!

Check the other equations just to make sure this is the only option:

2 = 5^(- - 1)

Negative + Negative = Positive

2 = 5^1

2 = 5

Incorrect.

2 = 0.5^(- - 1)

2 = 0.5^1

2 = 0.5

Incorrect.

This means our first solution is the only solution.
