1 99 AP Calculus AB: Section I 9 Minutes Scientific Calculator Notes: () The eact numerical value of the correct answer does not always appear among the choices given. When this happens, select from among the choices the number that best approimates the eact numerical value. () Unless otherwise specified, the domain of a function f is assumed to be the set of all real numbers for which f () is a real number.. If f( ) =, then f () = Which of the following represents the area of the shaded region in the figure above? d ( ( )) f ( ydy ) c ( b a) [ f( b) f( a) ] ( d c) [ f( b) f( a) ] b d f d f ( b) f ( a) a. n 5n lim n n n + is 5 noneistent AP Calculus Multiple-Choice Question Collection 8 Copyright 5 by College Board.
