Lee follows the steps for graphing rational functions when sketching the function x-x-2 *+*and gets the graph given below. Lee is not convinced that his graph is correct. a) Provide feedback on this graph. Show work. b) State the domain and range of f (x). c) State the intervals where f(x) is positive and the intervals where f(x) is negative. d) State the intervals where f(x) is increasing and the intervals where f (x) is decreasing
