4) Assume that f(t) is continuous on [a, b] and that u = g(t) is continuously differentiable on [a, b], then ['s(a() ,' () at = ['s(u) du. a) True b) False 5) Assume that f is continuous and strictly increasing on [0, 1] with f(0) = 0 and f(1) = 1 with fo f(t)dt = 1. Assume that g is the inverse of f on [0, 1]. Then So g(t) dt = 3. a) True b) False 6) If G(x) = In(t) dt then G'(x) = 273e-72. a) True b) False 7) Let R be the region bounded by the graphs of f(x) = cos(x) and g(x) = sin(x) where 0
