Question
Let fand g be the functions defined by f(x)= x+eper + 1, and g(x) andg(x) = - the two regions enclosed by the graphs off and g shown in the figure above. a) Find the sum of the areas of regions Q and R. b) The region Q is the base of a solid whose cross sections perpendicular to the x-axis are squares. Find the volume of the solid. c) The vertical line x = k divides region R into two equal regions with equal areas. Write, but do not solve, an equation involving integral expressions whose solutions give the value k.
