1. **State the problem:** We are given a piecewise function
$$f(x) = \begin{cases} 3, & x \leq -1 \\ (x-1)^2, & x > -1 \end{cases}$$
We need to evaluate the left-hand limit as $x$ approaches $-1$, i.e., $\lim_{x \to -1^-} f(x)$.
2. **Recall the definition of left-hand limit:**
The left-hand limit $\lim_{x \to a^-} f(x)$ is the value that $f(x)$ approaches as $x$ approaches $a$ from values less than $a$.
3. **Apply the definition to our function:**
For $x \leq -1$, $f(x) = 3$. So as $x$ approaches $-1$ from the left, $f(x)$ is constantly 3.
4. **Evaluate the limit:**
Since $f(x) = 3$ for all $x \leq -1$,
$$\lim_{x \to -1^-} f(x) = 3.$$
