Given information

The given function is and the interval is with  

Step-by-step explanation

Step 1.

step

With computing the left and right Riemann Sums for the function  

We can see that the graph is curved upwards that means that the left point Riemann sum will underestimate the Riemann sum and right point Riemann sum will over estimate the integral. Since with the Riemann sum was   we can say that the sum was accurate to tow decimal places. Since it falls that close to the true integral.

Thus, this estimate shows that
