1 f (x) dx = 8 and z 6. 4 f (x) dx = 12, nd z 4. 3: below is the graph of a function. Solution: f: find lim x 2(cid:18)x2 2x x 2 (cid:19) . a) 1: does not exist, find f (x) where f (x) = ln(x2 + 2). a) 2x ln(x2 + 2) b) x x2 + 2 e) ln x2 + 2 f) ln 2x c) g) 2x: x ln(x2 + 2, none of the above. Solution: c: find an antiderivative of f (x) = 3x2 , x3 , x2 + 2 x2 : x3 , x3 . 2 x: let g(x) be the function g(x) = z x2 x t cos t dt. Find the derivative g (x). a) c) sin x2 sin x. 2x3 cos x2 x cos x b) d) cos x2 + x2 sin x2 cos x x sin x. 1: x2 cos x2, none of these.
