Question 3 (7 points): Letf(x) = 1n(ex25x10 + 1) a) (2 points) Find f '(x) and use it to nd all stationary points of f (x) b) (3 points) Find f "(96) and use it to determine if the stationary points you found in part (a) are local minima 0r maxima. You do not need to simplify f "(x) C) (1 point) Does f ()6) have a global minimum? Explain d) (1 point) Does f (x) have a global maximum? Explain
