Select the correct answer. Function f is an exponential function that has an initial value of 64 and decreases by 50% as x increases by 1 unit.

Function g is represented by the table.

Which statement correctly compares the two functions on the interval [0, 4]?

A. Both functions are decreasing, but function g is decreasing at a faster average rate on that interval.

B. Both functions are decreasing, but function f is decreasing at a faster average rate on that interval.

C. Function f is decreasing, but function g is increasing, on that interval.

D. Both functions are decreasing at the same average rate on that interval.
