Overview
Please help, I have no idea how to sketch graphs to save my life. Can you please explain, step by step, in the simplest way possible, what needs to be done? For questions 2 and 3 on page 1, I only need help with the sketching part please, I already know how to do the rest. The questions on pages 2 and 3 are about integration. I have no idea how to sketch a curve meeting a line or how to show two curves intersecting and the area bla bla. How am I supposed to know whether the curve is at a minimum or a maximum? Also, if you have any tips or hacks for sketching, I would be immensely grateful. Thank you
