Question 17 N R Figure 2 Figure 2 shows a sketch of part of the curve C with equation y = x3-10x2+ kx where k is a constant equal to 28 . The point P on C is the maximum turning point. The line through P parallel to the x -axis cuts the y -axis at the point N. The region R is bounded by C, the y -axis and PN, as shown shaded in Figure 2. Use calculus to find the exact area of R
