I.USING RIEMANN SUMS

Approximate the area beneath the curve and above the x-axis using (a) Left Riemann Sum, (6) Right Riemann Sum, and (c) Midpoint Riemann Sum. y=x from x = 0 to x = 2, use / = 4. + 2 from x = 0 to x = 4, use n = 4. 2. y x +5 from x = 0 to x = 2, use n = 2. 3. 1 =-Find the area enclosed by the given curve, the x-axis, and given lines. 1. +10, x =1 and x = 3 2 . 1=x - 8, x = -1 and x = 2 3. 1 = - X-+6, x = -4 and x = 4 4. 1 = x - 6, x = -2 and x = 2 5. J=-x*+8, x = - 1 and x = 2Find the area of the region bounded by the given curve and line. 1. y = x andy = 4 2. J = x +3 and y = 7 3. y = x andy = 2x +3 4. y = 2x andy = 4x +6 5. 1= -x and y +6 = x
