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 src="https://sciemce.com/media/4/ppg__tttt0624190759__f1q14g5.jpg" style="vertical-align: -4.0px;" />, or y = 
, 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 = 
. (ii) Sketch a graph of function p using part (i) as an aid. 
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.
