I need help with these calculus questions:

WeBWork 5 - Topics 10 - 12: Problem 1 (1 point) Let f(z) da = -10, f(x) da = -11, 9(x) da = -1, 9(x) da = -8, Use these values to evaluate the given definite integrals. a) (f (z ) + g (x) ) du = b) ( f ( z ) - g ( x ) ) du = a / , ( 3 f ( 2 ) + 2g ( 2 ) ) da = d) Find the value a such that (af(z) + g(z)) do = 0. a = Note: You can earn partial credit on this problem.WeBWork 5 - Topics 10 - 12: Problem 2 (1 point) Find the function f(x) described by the given initial value problem. f"(x) = 0, f'(-2) = 3, f(-2) =-5 f (2) =WeBWork 5 - Topics 10 - 12: Problem 3 (1 point) a) If F(a) = t dt, then F' (x) = 16 10 b) If F(2) = 1 t dt, then F' (a) = C) If F(x) = + dt, then F' (x) = . x2+1 c) If F(a) = + dt, then F' (x) = 2+ cos * Note: You can earn partial credit on this
