The function represents the rate of flow of money in dollars per year. Assume a 10-year period and find the present value.

f(x) = 2300x - 190x2 at 10% compounded continuously

For your continuous cash flow function f(x), the integral

\int_0^{10} f(x)e^{-0.1x} \ dx

will give you your PV for the 10-year period.
