1. Find the derivatives of each of these functions: (2 marks each) a. y = In (4x2 + 4) b . y = ; e5x c. y = 25x+ (In(5x + 1) ) 4x3 d. y = e5x +4 2. Use the process of implicit differentiation to find given that x ey - yet = 0. (4 marks) 3. Use curve sketching methods, sketch the graph of the function given by the equation y = Make sure that you include all steps, charts, and derivations details. (10 marks) 4. Use logarithmic differentiation to find the derivative of the function y = (2:+5) (5x2-2x) V2x+5 (6 marks)
