two questions thanks

Find the intervals of increase and decrease of the function f(x) = x - 2 sin x. Time left 1:28:59 Select one: a. f is increasing on (~ + 2nn, -- + 2(n + 1)) and decreasing on (-2 + 2nn, , + 2nn) for integers n b. f is increasing on ( + 2nn, -7 + 2(n + 1)x) and decreasing on (-- 3 + 2 n , + 2nit ) for integers n C. f is increasing on ( + 2nn, - -+ 2(n + 1)x) d. f is increasing on ( + 2nat, -_ - + 2nT) Find the slope of the curve exy In x y =N+ - at (e, 1/e). Select one: a. V R N Ob. y = O C. V = 202 1 V = 2
