у=х^2(6-х) Найдем производную y'=2x(6-x)+ $x^{2}$ *(-1)=12x-2 $x^{2}$ - $x^{2}$ =12x-3 $x^{2}$ Приравниваем к 012x-3 $x^{2}$ =03x(4-x)=03x=0 или 4-x=0x=0 x=4Оба значения входят в отрезок [-1;5], поэтому подставим их в функциюy(-1)=1*7=7y(0)=0y(4)=16*2=32y(5)=25*1=25Ответ: y наибольшее=32, у наименьшее=0

Corporation

A corporation
is a business organization authorized by the state to conduct business and
is a separate legal entity from its owners. It is the dominant form of
American business because it makes it possible to gather large amounts of
capital together.
Before a
corporation may do business, it must apply for and receive a charter from
the state. The state must approve the articles of incorporation, which
describe the basic purpose and structure of the proposed corporation.
The
stockholders usually meet once a year to elect directors and to carry on
other important business. Each share of stock entitles its owner to one
vote. A stockholder who cannot attend the meeting can legally authorize to
vote his or her shares by proxy.
Management of
a corporation consists of the board of directors who decide corporate
policy, and the officers, who carry on the daily operations. The board is
elected by the stockholders, and the officers are appointed by the board.
Some specific
duties of the board of directors are to declare dividends, authorize contracts,
decide on executive salaries, and arrange major loans with banks. Management`s
main means of reporting the corporations financial position and results of
operations is its annual report.
The
corporation form of business has several advantages over the sole
proprietorship and partnership. It is a separate legal entity and offers
limited liability to the owners, ease of capital generation and ease of
transfer of ownership. In addition, it allows centralized authority,
responsibility and professional management.
The
corporation form of business also has several disadvantages. It is subject
to greater government regulation and double taxation. In addition,
separation of ownership and control may allow management to make harmful
decisions.
