6. Find the exact area of the region bounded by the given equations if possible. If you are unable to determine the intersection points analytically, use a calculator to approximate the intersection points with three decimal places and determine the approximate area of the region. y = V1 - x andy = x + 2x+ 1 7. The largest triangle with a base on the x-axis that fits inside the upper half of the unit circle y + x = 1 is given by y = 1 + x and y = 1 - x. See the following figure. What is the area inside the semicircle but outside the triangle? 1.5 0.5 . -1.5 -1 -0.5 0 0.5 1.5 X -0.5
