Answer:

C) Exponential decay

Explanation:

The groundnumber is less then 1 so by that alone, it must be decay of some sort...

The x is in the exponent, so now you have found your answer. C) Exponential decay.

Because 17/20 = 0.85, you can write the function as:

f(x) = (17/20)^x

Please see graph, which confirms answer C.
