Question 1 please

1) Find the derivative of y = log3 x. 2) Find the derivative of f (x) = 5x2 - 2log2 x. 3) Find the equation of the tangent line to y = log4 x when x = 1. 4) If y = 3e2t, find y". What does your answer tell you about the graph of y? 5) If f(x) = -3*, find f"(x). What does your answer tell you about the graph of f
