From Sabahat: Hi, I have enclosed a diagram.
The diagram shows the curve y=(2x-5)4. The point P has co-ordinates (4,81) and the tangent to the curve at P meets the x-axis at Q.
Find the area of the region (shaded in the diagram) enclosed between the curve, PQ and the x-axis . (Please note that the equation y is read as y=2x -5 whole raise to power 4.) Answered by Stephen La Rocque.
From Esther: Find the area of the region enclosed by the graphs of y = x3-6x and y = -2x between their points of intersection. Answered by Harley Weston.
