I dont see where to go without the 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...
