Attached is a picture of some True/False questions I need help with. a through j.

1. True/False (a) Ilfldx can be estimated by using a Riemann sum. 7 x (b) Riemann sum approach is applicable only when the function is positive. (c) A definite integral exists aslgngas it is continuous, and bounded over the interval of interest (d) F(x) is an antiderivative Lx), if Ibf(x)dx =IbF'(x)dx =F(b)-F(a) (e) _ ii =n(n+1)/2. S 1 (fl _ IfUde = _.-f(x)dx by definition. 1 5 1 (g) _ j xdx = 0 71 (h) Following the Antiderivative and Definite Integrals conjecture in l Sect 4.4, we have fizdx = 2, because id) = i2. ,1 X dx x x t b L' (i) For any integrable function f, If(x)dx =If(x)dx+If(x)dx where a
