Use lower and upper sums (left end and right end sums) to approximate the area of the region under the curve on the interval [0, 1]. Use 2 rectangles of equal width (n=2). Round your answer to two decimal places. 0.5 f(x)=√ Lower sum with 2 f(x)=√, Upper sum with = 2 (The diagram shows lower and upper sums for the square root function using n=2 equal subintervals.) Lower sum = L₂ = A Upper sum -R₂=-
