This is similar to a problem in the textbook.

$\backslash$table$[[$Time $($months$),01,2,3,4,5],[$Rate pollutants are escaping $($tons$/$month$),47,11,14,18,33]]$

Use this data to sketch a smooth curve relating the two variables.

Draw rectangles on the graph you drew to help you underestimate the total pollutants that escaped during the first month. What underestimate did you obtain?

$$ tons

Draw rectangles on this graph to help you overestimate the total pollutants that escaped during the first month. What overestimate did you obtain?

$$ tons

Draw rectangles on this graph to help you underestimate the total pollutants that escaped during the whole time. What underestimate did you obtain?

$$ tons

Draw rectangles on this graph to help you overestimate the total pollutants that escaped during the whole time. What overestimate did you obtain?
