Lee follows the steps for graphing rational functions when sketching the function f()= and gets the graph given below. Lee is not convinced that his graph is correct. SE= 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
