3.(10pts) Consider the polynomial function 10 x 2x f(x) = 3 73 + 1 over the interval [0, 9). Compute the exact area under the curve of each function by evaluating the limit of a right hand Riemann Sum, i.e. lim Rn. You must apply one or more of the summation identities before taking the limit to infinity. k = kn; 5 i = n(n + 1). 2 - n(n + 1)(2n+1) 5 13 = 712 ( 1+ 1 )2 i-1 2 i-1 6 4
