Complete this assignment by hand and do not type your answers. You may NOT use a graphing calculator to determine the shape of the graph, but you may use a calculator for basic arithmetic to help you find values of the function. Make sure you are showing all your steps clearly. When you upload your work into the LMS, make sure your work is vertical so it can be easily viewed and graded. Follow the 5 Steps for Curve Sketching to sketch the graph of the function. (20 points) f ( x ) = 3 x2 - 3x Step 1: Find the critical points and plot them on the graph on the next page. a. Find the first derivative. b. Set the first derivative equal to O and find where the first derivative does not exist. c. Plug the x-value of each critical point into the original function to find the y-value of the point itself
