finding f in this calculus problem?

f''(x) = x−2, x > 0, f(1) = 0, f(3) = 0

Whats f?

I know it starts with - ln(x), but I'm stuck after that.

I know to take the integral twice, but my answers aren't correct

Update:

it's f''= x^-2, not x-2

    Don't forget the constants from integration.

    f(x) = - ln(x) + Ax + B

    Then use the given values f(1) and f(3) to solve for A and B.
