Solve the problem.A retail chain sells washing machines. The retail price p(x) (in dollars) and the weekly demand x for a particular model are related by the function p(x) = 625 - 5, where 50 ? x ? 500. (i) Describe how the graph of the function p can be obtained from the graph of one of the six basic functions: y = x, y = , y =

A. (i) The graph of the basic function y =  is
vertically expanded by a factor of 625,
and shifted up 5 units.
(ii)

B. (i) The graph of the basic function y =  is
vertically expanded by a factor of 5,
and shifted up 625 units.
(ii)

C. (i) The graph of the basic function y =  is
reflected in the x-axis and vertically
expanded by a factor of 5.
(ii)

D. (i) The graph of the basic function y =  is
reflected in the x-axis, vertically expanded
by a factor of 5, and shifted up 625 units.
