I need help on these 3 calculus questions:

Question 1 (1 point) Let f(x) = x + sin(x). Then the derivative of the inversef _1(x) atx = 0, (f '1)'(0), equals 0% 02 O The derivative does not exist. 0 l 2 Q o Question 2 (1 point) Let f(x) = 6 sin (x2). Then f' (x) equals 12xcos-1(x2) O 1 - x4 O 6 1 - x2 O 12x V1 - x2 12x 1 - x4Question 3 (1 point) Let f be a function which is one-to-one and differentiable on (-co, co). The following table gives some information about f f(x -1 (a dx f (a da 1 10 10 80 50 100 100 200What can we conclude about the missing data? Of-1(10) = -1/8 O d f - 1 ( 1 ) = - 4 Of-1(100) = 8 O dx J f-1(80) = 1/5 O d f-1(200) = 800
