Tìm đạo hàm \(f'\left( x \right)\) của hàm số \(f\left( x \right) = {x^2} - 3\sqrt x + \frac{1}{x}\).
A.\(f'\left( x \right) = 2x + \frac{3}{{2\sqrt x }} - \frac{1}{{{x^2}.}}\)
B.\(f'\left( x \right) = 2x - \frac{3}{{2\sqrt x }} + \frac{1}{{{x^2}.}}\).
C.\(f'\left( x \right) = 2x - \frac{3}{{2\sqrt x }} - \frac{1}{{{x^2}.}}\)
D.\(f'\left( x \right) = 2x + \frac{3}{{2\sqrt x }} + \frac{1}{{{x^2}.}}\)
A.\(f'\left( x \right) = 2x + \frac{3}{{2\sqrt x }} - \frac{1}{{{x^2}.}}\)
B.\(f'\left( x \right) = 2x - \frac{3}{{2\sqrt x }} + \frac{1}{{{x^2}.}}\).
