Graph 4: Explain in terms of your equation why there are no points on the graph for a/4

Graph Explain in terms of your equation why there are no points on the graph for 7/4 < O < 3K/I, and no points on the graph for 57/4 < < 77/4- Graph 7: Tell why there is a loop in the graph, i.e., why as 0 increases from O toward 27, the loop occurs. Graph 10: By using your calculator, determine if r(3r/2) < for O near to 37/2 but not equal to 3*/2, Does your answer justify calling the graph a "dimpled" litnucotl?
