Use the figures to calculate the left and right Riemann sums Ay for f on the given interval and the given value of n. f(x) = = 5- f(x) = _+ 3 on [1,5]; n =4 X X 0 1 2 4 5 Ay O 5 - f(x ) = = + 3 The left Riemann sum for f is . (Round to two decimal places as needed.) The right Riemann sum for f is . (Round to two decimal miaces as needed.)
