Hi. the answer of this question has been given, but I cannot calculate the correct answers for (d) (e) (f). Please help me make the detailed processes. Thank you

Q77. First and Second Derivatives. Find the first and second derivatives of the functions: (a) f(x) = 24 - 323 + 16x (b) h(2) = Vaz+1 ( c ) f (20 ) = 1 - x (d) y = (1 - 22) 3/4 (e) f (x) = e2x-sin(5x) (f) g(x) = cosec(ac)A77. First and Second Derivatives. (a) f'(x) = 4x3 - 9x2 +16, f"(x) = 12x2 - 18x (b) h'(20) = 2/ (Vac2 + 1), h"(2) = 1/(202 + 1) 3/2 (c) y' = 1/(1 - x)2, y" =2/(1 -a)3 (d) y' = -3x(1 -22)-1/4, y" = 3(1-22)-5/4(202 -2) (e) f'(x) = (2 - 5 cos(5x))e2x-sin(5x), f"(x) = (25 sin(5x) + (2 - 5 cos(5x))2 )2x-sin(5x) (f) g'(a) = - cosec(x) cot(a), g"(x) = cosec3 (a) + cosec(a) cot2(ac)
