To find the derivative of the function \( f(x) = \frac{3}{\sqrt{2x - 1}} \), we will use the **chain rule** and **quotient rule**.

### Step-by-step solution:
Given:
\[
f(x) = \frac{3}{\sqrt{2x - 1}}
\]
We can rewrite the square root in exponent form:
\[
f(x) = 3(2x - 1)^{-\frac{1}{2}}
\]

Now, apply the **chain rule**:
1. Differentiate the outer function: \( 3(2x - 1)^{-\frac{1}{2}} \). The derivative of \( (2x - 1)^{-\frac{1}{2}} \) is:
\[
\frac{d}{dx} \left[ (2x - 1)^{-\frac{1}{2}} \right] = -\frac{1}{2}(2x - 1)^{-\frac{3}{2}} \cdot \frac{d}{dx}(2x - 1)
\]
2. Now, differentiate the inner function \( 2x - 1 \):
\[
\frac{d}{dx}(2x - 1) = 2
\]

3. Combining these, the derivative becomes:
\[
f'(x) = 3 \cdot -\frac{1}{2}(2x - 1)^{-\frac{3}{2}} \cdot 2
\]
Simplifying:
\[
f'(x) = -\frac{3}{(2x - 1)^{\frac{3}{2}}}
\]

Thus, the derivative of the function \( f(x) = \frac{3}{\sqrt{2x - 1}} \) is:
\[
f'(x) = -\frac{3}{(2x - 1)^{\frac{3}{2}}}
\]
