1. Function f(x, y) has values in the following table: 1 1.1 1.2 |0 21 1 -1 y 0.2 4 2 0.4 6 4 Find the Riemann sums which are reasonable upper and lower estimates for| f(x,y)dA where G is the rectangle 1

Consider the function f(x) = −²+ +4. 4 x² In this problem you will calculate ["(-33 0 = The summation inside the brackets is Rn which is the Riemann sum where the sample points are chosen to be the right- hand endpoints of each sub-interval. Calculate Rn for f(x) = - + 4 on the interval [0, 4] and write your answer as a function of n without 3 signs. R₂ lim Rn n→∞ = +4) dx by using the definition ← ·b ["* ƒ(2) dx = lim [ƒ(2.)Az] n→∞ any summation
