Nguyên hàm của hàm số \(f\left( x \right) = {x^2} - 3x + \frac{1}{x}\) là:
A.\(\int {f\left( x \right)} dx = \frac{{{x^3}}}{3} + 3\frac{{{x^2}}}{2} + \ln \left| x \right| + C\).
B.\(\int {f\left( x \right)} dx = \frac{{{x^3}}}{3} - 3\frac{{{x^2}}}{2} - \ln x + C\)
C.\(\int {f\left( x \right)} dx = \frac{{{x^3}}}{3} - 3\frac{{{x^2}}}{2} + \ln \left| x \right| + C\).
D.\(\int {f\left( x \right)} dx = \frac{{{x^3}}}{3} - 3\frac{{{x^2}}}{2} - \ln \left| x \right| + C\).
