For the following problems use a Left Hand Riemann sum. Feel free to use your calculator on a majority of the calculations. a. Approximate the area under the curve f(x) = - 0.3x2 + 22 between * = 1 and & = 7 using 6 rectangles. L/6 = b. Approximate the area under the curve f( x ) = - 0.3x2 + 22 between x = 1 and x = 7 using 12 rectangles. L/12 = c. Approximate the area under the curve f(c ) = - 0.3x* + 22 between * = 1 and * = 7 using 60 rectangles. L/60 =
