Q1 Let R be the region enclosed by the functions y = f(x), y = g(x), y = h(x) and the r-axis as shown below: ( 1, 1) -0.8 y=g(x) -0.6 (1.5, 0.5) y=f(x) -0.4 -0.2 y=h(x) 0 2 0.4 0.6 0.8 1/2 1.4 1.6 Your answers for the parts below should only involve f, g, h, f-1, g-1, h-1 (as needed). Do not try to actually find equations for these functions! a 6 points Write an integral (or sum of integrals) in a that gives the area of the region R. b 6 points Write an integral (or sum of integrals) in y that gives the area of the region R
