Apply the quotient rule to find the derivative of each of the following functions. 3x2 a) f(x) x +1 { fx) = [ (3 x^2) / (x^2 + 1) ] e* b) g(x) !! sin x { g(x) = [ (e^x) / (sin x) ] } QUESTION 4 For each of the following functions, find the first and second derivatives. a) product rule f(x) = ex sin x { f(x) = e^x sin x b) quotient rule 2x+1 g(x) -2 { g(x) = [(2x + 1)/(3x- 2)] }
