(adsbygoogle = window.adsbygoogle || []).push({}); Please help!!! Struggling with finding the area using upper & lower sums!!

I can't load the picture on here so I will explain it the best I can...

It is the graph of 1/x and there are 5 subintervals starting at x = 1 and ending at x = 2.

It says to use upper and lower sums to approximate the area of the region. Their widths are equal.

So first I have to find the left and right endpoints I think...but I am still not understanding how to figure them out.

My guess is...

Left: 5(i-1)/n

Right 5i/n
