A company manufactures and sells in-line skates. Its financial department has established the price-demand function
p(x)=190 - 0.013(x - 10)2 10 ≤ x ≤ 100
where p(x)is the price at which x thousand pairs of in-line skates can be sold.
(A) Describe how the graph of function p can be obtained from the graph of one of the basic functions in Figure 1 on page 60.
(B) Sketch a graph of function p using part (A) and a graphing calculator as aids.
