PLEASE HELP, BEEN STUCK FOR AN HOUR!! 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.

x01234
g(x)7543271915

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

A.
Both functions are decreasing at the same average rate on that interval.
B.
Function f is decreasing, but function g is increasing, on that interval.
C.
Both functions are decreasing, but function f is decreasing at a faster average rate on that interval.
D.
Both functions are decreasing, but function g is decreasing at a faster average rate on that interval.
