Find the equation of the function f whose graph passes through the given point. (Remember to use ln |u| where appropriate.)

f'(x) = x^3 − 4x^2 + 3/ x − 3 ; (4, −5)
f(x) =

remember the integral of 3/x is ln|x|

the rest is easy,
don't forget to add c to the end of the integral, sub in (4,-5) to find c
