Find the area bounded by the parabola y^2=4x and the line y=2x-4. Use vertical representative rectangles (integrate with respect to x) and horizontal representative rectangles (integrate with respect to y). the answer is 9 square units ... i just need to know how to get to that.
You may find it simpler to rotate the curve and the line a quarter turn anti-clockwise around the origin.
This gives y = x^2/4 and y = 1/2x + 2
They intersect at x = -2 and 4.
Find the definite integral over the interval (-2, 4) of 1/2x + 2 - x^2/4.
This gives 9 units
ur dumb ok???
