Question

Does the function f(x) = (0.85)\ represent exponential growth, decay, or neither?
A) Exponential growth
B) Neither
OC) Exponential decay
D)
Impossible to determine with the information given.

Answer 1

Answer:

C) Exponential decay

Step-by-step 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.
