What does

represent? Width

Let

Use what you know to find the sum of the areas of the. right-endpoint rectangles of on. The

in the express raises the function up . So the total area is increased by because the base was . Find the sum of the

right-endpoint rectangles for for. Since the whole graph is raised up

and the base is still , how much more area would the new function have than ?
