10. Find the following limits: A. um x: 25 x _' '5 2x' + 10x l 1. For the function f(x]detined by the graph below, with each mark representing one unit, evaluate the following expressions, approximating if necessary: D) lim f(x) == x-Mr E) At what nu1nber(s) is x) discontinuous? 12. Refer to the gure to the right which shows the graph of f '(x). This is not the graph of f(x)! A. Where does the graph of x) have a maximum (if any)? B. Where is the graph of x) increasing? C. Where does the graph of f(x) have an inflection point
