1. **State the problem:** We need to find the values of the piecewise function $$f(x) = \begin{cases} x + 1 & \text{if } x \leq -1 \\ x^2 & \text{if } x > -1 \end{cases}$$ at $x = -3$, $x = 0$, and $x = 2$.
2. **Understand the function:** The function has two parts:
- For $x \leq -1$, use $f(x) = x + 1$.
- For $x > -1$, use $f(x) = x^2$.
3. **Calculate $f(-3)$:** Since $-3 \leq -1$, use $f(x) = x + 1$.
$$f(-3) = -3 + 1 = -2$$
4. **Calculate $f(0)$:** Since $0 > -1$, use $f(x) = x^2$.
$$f(0) = 0^2 = 0$$
5. **Calculate $f(2)$:** Since $2 > -1$, use $f(x) = x^2$.
$$f(2) = 2^2 = 4$$
**Final answers:**
- $f(-3) = -2$
- $f(0) = 0$
- $f(2) = 4$
