Extracted text: 5. (a) If f(x) = x · 2", give an estimate of the net area of the region bounded by fand the x-axis on [1, 5] using the: i. L̟ Riemann sum ii. L, Riemann sum iii. R¸ Riemann sum 4 iv. M, Riemann sum (b) Does the R¸ Riemann sum give an overestimate or an underestimate of the exact area? 4
