WebAny right-hand sum will be an over-estimate of the area of R. Since f is increasing, a right-hand sum will use the largest value of f on each sub-interval. This means any right-hand sum will cover R and then some. We see that if f is always increasing then a left-hand sum will give an under-estimate and right-hand sum will give an overestimate.
