Do you mean, right-endpoint and left-endpoint rectangles?

I'm assuming that's: Left end or right end rule?

It will specifically state what rule to use in the question.

It doesnt matter? i dont think so. As either rule would give you the same result, but some graphs you have to ultillize both...

Do you mean, if the question asks you to find "left-endpoint" rectangles, you don't understand how to graph it?

I'm not sure if that's what you mean, but if it is, you just need to draw a rectangle that has the top-left corner touching the graph.

Does that help?
