1. **Problem:** Determine whether the function $f(x) = 3x^2 - 2x + 5$ is continuous at $x = 2$.
2. **Recall the definition of continuity at a point:** A function $f$ is continuous at $x = a$ if:
$$\lim_{x \to a} f(x) = f(a)$$
This means the limit of the function as $x$ approaches $a$ must exist and be equal to the function's value at $a$.
3. **Evaluate $f(2)$:**
$$f(2) = 3(2)^2 - 2(2) + 5 = 3 \times 4 - 4 + 5 = 12 - 4 + 5 = 13$$
4. **Evaluate the limit $\lim_{x \to 2} f(x)$:** Since $f(x)$ is a polynomial, it is continuous everywhere, so the limit is simply the value at $x=2$:
$$\lim_{x \to 2} f(x) = f(2) = 13$$
5. **Conclusion:** Since the limit equals the function value at $x=2$, $f$ is continuous at $x=2$.
\boxed{\text{The function } f(x) = 3x^2 - 2x + 5 \text{ is continuous at } x=2.}
