8. Express in terms of Definite Integrals the areas of the following regions: (a) The region between the graph of y = 6x3 + 7x - 3 and the r-axis (b) The region between the graphs of y = 6x3 + 7x - 3 and y = 4x3 - 3 (c) The region between the graphs of y = 6x3 + 7x -3 and y = 4x2 - 3 and the vertical lines 2 -4 and = =0 (d) The shaded region below where the labeled points are A : (-7,5) and B : (-11,4/3), the straight line L is 2x + y = -9, and the curved line C' is y "-45 1+3 Use Absolute-Value Signs appropriately; do not calculate the Definite Integrals. 15% A KL B
