(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 equationy = 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, n - 20 2. Use your graphing calculator to see the graph of y = 4 where 1 sxs 11. 2.6 2.0 1.5 1.0 D.6 10 12 Insert a screen capture of the spreadsheet with data for the new equation.
