9 The table gives the values of a function obtained from an experiment. Use them to estimate / f(x) dx using three equal subintervals with right endpoints, left endpoints, 3 and midpoints. If the function is known to be an increasing function, can you say whether your estimate is less than or greater than the exact value of the integral? A less than A greater than A one cannot say 9 (b) Estimate / f(x) dx using three equal subintervals with left endpoints. 3 L3 If the function is known to be an increasing function, can you say whether your estimate is less than or greater than the exact value of the integral?
