anybody?

Answer 5

You need a lower sum, not the lower sum, right?

Answer 6

yes , i need the lower sum

Answer 7

But there's not just one lower sum. By the way this is about approximating the area under graph, right?

Answer 8

yes

Answer 9

what do you mean theres not just one lower sume?

Answer 10

You can have a lower sum with one rectangle or 2 or 10 etc.

Answer 11

i understand, but my book is asking me to estimate the area under the function using a lower sum with four rectangles.
