A. Function fis decreasing, but function g is increasing, on that interval.
B. Both functions are decreasing at the same average rate on that interval.

C. Both functions are decreasing, but function gis decreasing at a faster average rate on that interval.

D. Both functions are decreasing, but function fis decreasing at a faster average rate on that interval.
