Note that questions 1, 3, and 4 were identical on both exams. We've listed all 6 AB questions first, and then the three BC only questions. By the Fundamental Theorem of Calculus, Z 2 6 f0(x)dx= f( 2) f( 6) = 7 f( 6). But the value of this integral is the area of a triangle whose base is four and whose altitude is two, so 7 f( 6) = 4, and f( 6) = 3. Similarly, Z 5 2 f0(x)dx= f(5) 7, while the value of this integral is the area of a triangle of base three, altitude two, less the ... Visit College Board on the web: collegeboard.org.
