Given y = 3x –- 2x +1, y =-x² + 2x +1 and a straight line y = 0.5x ; where x>0,
1. Sketch the curves and the line on the same coordinate axes.
2. Shade the area where the region of R1, bounded above by the curves, y= 3x – 2x +1
and bounded below by the line y=0.5x within 0<x<1 and R2, bounded above by
y = -x² + 2x +1 and bounded below by the line y= 0.5x within 1<x<2.
3. Determine the coordinate of the points of intersection at the first quadrant.
4. From your answer at (2),
a) calculate the area of the regions R1 and R2.
b) find the volume of the solid formed when R1 is revolving about the x-axis.
