5. a. [3 points] Use Geogehra to sketch the graph of f{x) - ix: +1. Copy the graph onto the grid to the right. Shade the area between the graph and the x-axis on the interval [-4, 3]. h. (8 points] Now use upper and lower sums as in question 4 to estimate the area under the curve on the interval [-4. 3]. Then ll in the table below writing your answers to two decimal places: c. [1 point] After looking at the values in the table, make your own estimate as to what the actual area is . Estimated area = d. [3 points] Use the method given in 4d along with Geogehra to calculate the exact area. Then ll in the 2 boxes and the line: 5-1 Exact area =|:rg?rz + lid): - IS. a. [3 points] Use lGeogehra to sketch the function 1 x = Ex} - 31' on the grid at the right. Shade the area between the graph and the xaxis on the interval [-3, 3]. h. [3 points] Use the method given in 4d along with Geogehra to calculate the exact area Then ll in the 2 boxes and the line: Exact area = gf 3.rdr - c. [2 points] Whyr do you think you got the answer above
