Consider the following.
The xy-coordinate plane is given. A line y = x - 5, a curve y = x^2 - 5x, and a shaded region are graphed.
- The line enters the window at y = -5 on the negative y-axis, goes up and right, passes through the point (1, -4) crossing the curve, crosses the x-axis at x = 5 crossing the curve, and exits the window in the first quadrant.
- The curve enters the window at the origin, goes down and right becoming less steep, passes through the point (1, -4) crossing the line, changes direction at the point (2.5, -6.25), goes up and right becoming more steep, crosses the x-axis at x = 5 crossing the line, and exits the window in the first quadrant.
- The area below the line and above the curve is shaded.
(a) Find the points of intersection of the curves.
(x, y) = (smaller x-value)
(x, y) = (larger x-value)
(b) Form the integral that represents the area of the shaded region.
(c) Find the area of the shaded region. (Give an exact answer. Do not round.)
