Hello, I'm having issues with letter c, d, e and f of this problem. Please help [step by step please]:

Differentiate the following functions Remember that the natural logarithm of x would be entered as In(x) in WebAssign. HINT: You may be able to simplify one or more of the following functions using the rules of logarithms BEFORE taking the derivative. a. f (x) = In (4 x) f' ( x ) = 4/(4x) b. f (x) = In (x +3) f' ( x) = 1/ (x+3) c. f (x) = x In x f'(x) = 15 X a J (x) = In x f' ( x ) = f (x) = In x + 10 e, x +4 f' ( x ) = 4. f (x) = In (4 Vx) f' ( x ) =
