Part A Your supervisor has finally given you the equation! It's } = 149- - 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 = ; butg 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 = ing where 1 sxs 11. 2.5 2.0 1.5 1.0 0.5 2 6 8 10 12Is this function increasing or decreasing? Based on this answer, can you determine whether there will be an underestimate or overestimate using the left endpoint?Evaluate #'+3 do . How does the value of the integral compare to your estimates?
