Exponential function f is represented by the table. x 0 1 2 3 4 f(x) 868 292 148 112 103 Function g is an exponential function passing through the points (0,800) and (4,0). Which statement correctly compares the two functions? A. Both functions are decreasing on [0, 4], but function g decreases at a faster rate. B. Only function g is decreasing on [0, 4], and only function f is positive on that interval. C. Both functions are decreasing on [0, 4], but function f decreases at a faster rate. D. Only function f is decreasing on [0, 4], and both functions are positive on that interval.
