Part A Your supervisor has finally given you the equation! It's y = = aug. Use your spreadsheet software and copy and paste the entire worksheet you previously completed. (Make sure you keep a copy of the items completed in Steps 1 and 2). Using the new copy, complete the following: 1. Use spreadsheet software and your previous setup to estimate the area below the curve for the equation y = sing between 1 and 11 using the following criteria: . Left endpoints, n = 5 Right endpoints, n = 5 . Left endpoints, n = 20 . Right endpoints, n = 20 . Midpoint, 7 = 20 2. Use your graphing calculator to see the graph of y = = + 3 1 - where 1 5 x 5 11. 2.5 2.0 1.5 1.0 10 Insert a screen capture of the spreadsheet with data for the new equation.
