2.Draw the graph of y = x2- 3x + 5 for 0 = x = 8. Take 1 cm to represent 5 units on the y-axis and 1 cm to represent 1 unit on the x-axis. Using four strips of equal width, use the mid- ordinate rule to estimate the area bound by the function y = x2-3x+5, the y-axis, the x-axis and line x = 8.
| Make a table of values for x and y. |
| On the grid provided draw the curve of y=x2 -3x + 5 and show the mid-ordinate in each rectangle. |
| The estimated area =h(y1+y2+y3+y4). |
| What is the size of the width (h) of each rectangle? |
| Use the graph to state the values of each mid-ordinate by filling the table below. |
| What is the estimated area? |
