Question

Approximate the area under graph (a) of f(x) = 3 / x2 over the interval [1,5] by computing the area of each rectangle to four decimal places and then adding. Approximate the area under graph (b) of f(x) = 3 / x2 over the interval [1,5] by computing the area of each rectangle to four decimal places and then adding. The area under graph (a) is approximately . (Round to four decimal places as needed.) The area under graph (b) is approximately . (Round to four decimal places as needed.) Approximate the area under graph (a) of f(x) = 3 / x2 over the interval [1,5] by computing the area of each rectangle to four decimal places and then adding. Approximate the area under graph (b) of f(x) = 3 / x2 over the interval [1,5] by computing the area of each rectangle to four decimal places and then adding. The area under graph (a) is approximately . (Round to four decimal places as needed.) The area under graph (b) is approximately . (Round to four decimal places as needed.)

Explanation / Answer

a) 3 +0.75+0.375 + 0.1875 = 4.3125 b) 1.5 +0.75 +0.375 +0.300 +0.1875+0.1675 +0.06+0.05 = 3.3900
