Answer

Simplify to find the derivative: \(f'(x) = 10x^2 - \frac{27}{2}x + \sqrt{x} - \frac{1}{2\sqrt{x}}\)

Steps

Step 1 :First, rewrite the function as \(f(x) = 4x^{\frac{5}{2}} - 9x^{\frac{3}{2}} + 2x^{\frac{1}{2}} - x^{-\frac{1}{2}}\)

Step 2 :Apply the power rule to find the derivative of each term: \(f'(x) = \frac{5}{2} \cdot 4x^{\frac{5}{2} - 1} - \frac{3}{2} \cdot 9x^{\frac{3}{2} - 1} + \frac{1}{2} \cdot 2x^{\frac{1}{2} - 1} + \frac{1}{2} \cdot x^{-\frac{1}{2} - 1}\)

Step 3 :Simplify to find the derivative: \(f'(x) = 10x^2 - \frac{27}{2}x + \sqrt{x} - \frac{1}{2\sqrt{x}}\)
