A right hand Riemann sum has been calculated for an increasing function between x=1 and x=2, using n=100.the value for the right hand sum is found to be 3.34 units. Which could be the actual area under the curve.

(B) 3.33

Step-by-step explanation:

The picture below shows a right-sum estimation for an increasing function. As you can see, the right-sum will overestimate the value of the actual area; therefore, the actual area must be slightly lower than the estimated value.

If the estimated value is 3.34, then slightly lower than that is 3.33.

its c or d   take a lucky guess my dude
