    Riemann Sum 3

    Use a Riemann sum to approximate the area under the graph of f(x) on the given interval with the selected points as specified.

    you have to approximate the value of a definite integral with no function information at all?

    ... or do you have a graph of f(x)?

    If you are not given a formula for f(x) then either get the values off a graph, as skeeter suggested, if you have one, or, if you have no information about f at all, just write your formula in terms of f(1), f(3), f(5), and f(7), leaving those instead of specific values.

    The answer in the back of the book is 40. I cannot see how to arrive at this answer...

    need to see the graph and your work.
