A function f(x) defined on (-oo, 3) U (3, co) is continuous throughout its do- main. Given the following information about the signs of the first and second derivatives of f, answer the questions below. No justification is required: only your final answers are necessary. f': + + -2 12 + 10 (a) On what interval(s) is f increasing? Your answer must use interval notation. (b) Give the location(s) (x-coordinate) of any relative minima. (c) On what interval(s) is f concave down? Your answer must use interval notation. (d) Give the location(s) (x-coordinate) of any points of inflection
