Apply the chain rule to find the derivative of each given function. 3x +2 a) f(x) = 4x - 1 f(x) = [(3x + 2) / (4x- 1) } b) g(x) = /(x2 + 5) cos x QUESTION 4 Chain Rule Apply the Chain Rule to find the derivative of the following function. [Note that since the function has several layers of composition, the derivative requires several iterations in applying the chain rule f(x) = //sin(e+ 4) { f(x) = 1/sqrt( e^[x^2 + 4]) } %3D Observe how this relates to the other form of the chain rule df df du dv dw dx du dv dw dx
