This question is on areas under a graph using integration methods.
Figure 2 shows a sketch pf part of the curve with equation y = 10 + 8x + x2 - x3.
The curve has a minimum turning point A.
The region R, shown shaded in Figure 2, is bounded by the curve, the y-axis and the line from O to A where O is the origin
Using calculus, find the exact area of R.
