3. (1 point) The following sum 14141414 n - - -+...+ 1+?z n 1+g n 1+E n 1+4" n is a right Riemann sum for a certain denite integral flbf(x)dx using a partition of the interval [1 , 1)] into n subintervals of equal length. Then the upper limit of integration must be: I) = and the integrand must be the function f (x) =
