1. The problem gives us the limits and function value at $x=2$ for the function $f(x)$ with domain $-2 \leq x < 4$.
2. We are asked to analyze the behavior of $f(x)$ near $x=2$ and understand continuity and limits.
3. The left-hand limit as $x$ approaches 2 is given as:
$$\lim_{x \to 2^-} f(x) = 2$$
This means as $x$ approaches 2 from values less than 2, $f(x)$ approaches 2.
4. The right-hand limit as $x$ approaches 2 is:
$$\lim_{x \to 2^+} f(x) = -2$$
This means as $x$ approaches 2 from values greater than 2, $f(x)$ approaches -2.
5. The function value at 2 is:
$$f(2) = 0$$
6. For a function to be continuous at $x=2$, the left-hand limit, right-hand limit, and function value must all be equal.
7. Here, the left and right limits are not equal ($2 \neq -2$), so the limit at $x=2$ does not exist (the two-sided limit does not exist).
8. Also, $f(2) = 0$ is different from both limits, so $f$ is not continuous at $x=2$.
9. The domain $-2 \leq x < 4$ means the function is defined from $-2$ up to but not including 4.
10. Summary: The function has a jump discontinuity at $x=2$ because the left and right limits differ and the function value is different from both.
Final answer: The limit $\lim_{x \to 2} f(x)$ does not exist due to differing one-sided limits, and $f$ is not continuous at $x=2$.
