1. (3 marks) If f(x)da = 37 and g(x)dx = 16, find (2f (x) + 3g(2)]dx. 2. (3 marks) If f(2) = 16, f' is continuous, and [, f'(x)da = 19, what is the value of f(6)? 3. (a) (2 marks) Evaluate the Riemann sum for f(x) = 6x3 - 3x, taking the sample points to be right endpoints and a = 0, b = 4 and n = 2 (b) (2 marks) Evaluate - 6x3- 3xdx
