Answer:

it's the first graph

Step-by-step explanation:

I just did the Unit Test 7 part 2: Exponential and Radical Functions and got a 100%

oh and for the exponential growth question that is similar to this one, that's also the first graph.

The exponential function from the table is y = 32(0.5)ˣ.

Exponential function

An exponential function is given by:

y = abˣ

where a is the initial value of y at x = 0, y, x are variables and b is the multiplication factor

From the first table, we can see that the value of y decreases 50% each time. Using point (1, 16):

16 = ab¹

ab = 16   (1)

Also point (2, 8):

ab² = 8

a = 32, b = 0.5

The exponential function from the table is y = 32(0.5)ˣ.
