F(x) = 6 (1/8)^x is an example of

An exponential growth function
A logarithmic growth function
An exponential decay function
A logarithmic decay function


  1. Answer:
    Exponential decay.  Your growth factor is 1/8, which is between 0 and 1.  Thus, the value is decreasing exponentially.
    If the growth factor is greater than 1, you have exponential growth.  Logarithmic functions will always contain a logarithm, so you can quickly rule out those options.
    Step-by-step explanation:
