The function f: R R is defined by f(x) = 4- and is plotted below, displaying the use of the trapezium rule to calculate the area under f on the interval [-2,2]. n 2.00 0 2 T 2 Area 8.00 3 -> (i) Using the slider in the graph above what is the approximate area under f on the interval [-2, 2] taking 8 subintervals? (n = 8 on the slider) Area = (ii) Now using the trapezoidal rule, calculate the approximation of the area under the graph on the interval [-2, 2] with 8 subintervals? (n = 8 on the slider). === Enter your power as a rational number of the form n/a
