1. **State the problem:** Find the value of the inverse function $f^{-1}(3)$ given $f(x) = 2x - 1$.
2. **Recall the formula for inverse functions:** To find $f^{-1}(y)$, solve the equation $y = f(x)$ for $x$.
3. **Set up the equation:** Let $y = 3$, so we have
$$3 = 2x - 1$$
4. **Solve for $x$:**
Add 1 to both sides:
$$3 + 1 = 2x$$
$$4 = 2x$$
Divide both sides by 2:
$$\frac{4}{\cancel{2}} = x \cancel{\frac{1}{2}}$$
$$x = 2$$
5. **Interpretation:** The inverse function value $f^{-1}(3) = 2$ means that when $x=2$, $f(x)=3$.
**Final answer:**
$$f^{-1}(3) = 2$$
