1. Planteamos el problema: calcular los límites dados usando los valores \(\lim_{x \to c} f(x) = -6\) y \(\lim_{x \to c} g(x) = \frac{1}{2}\).
2. Recordamos las propiedades de límites importantes:
- \(\lim (f(x)g(x)) = \lim f(x) \cdot \lim g(x)\)
- \(\lim \frac{f(x)}{g(x)} = \frac{\lim f(x)}{\lim g(x)}\) si \(\lim g(x) \neq 0\)
- \(\lim (f(x) + 2g(x)) = \lim f(x) + 2 \lim g(x)\)
- \(\lim (f(x))^2 = (\lim f(x))^2\)
3. Calculamos cada límite:
**29.**
$$\lim_{x \to c} [f(x)g(x)] = \lim_{x \to c} f(x) \cdot \lim_{x \to c} g(x) = (-6) \cdot \frac{1}{2} = -3$$
**30.**
$$\lim_{x \to c} \frac{f(x)}{g(x)} = \frac{\lim_{x \to c} f(x)}{\lim_{x \to c} g(x)} = \frac{-6}{\frac{1}{2}}$$
Simplificamos usando cancelación:
$$= \frac{-6}{\cancel{\frac{1}{2}}} \cdot \frac{\cancel{2}}{1} = -6 \cdot 2 = -12$$
**31.**
$$\lim_{x \to c} [f(x) + 2g(x)] = \lim_{x \to c} f(x) + 2 \lim_{x \to c} g(x) = -6 + 2 \cdot \frac{1}{2} = -6 + 1 = -5$$
**32.**
$$\lim_{x \to c} [f(x)]^2 = (\lim_{x \to c} f(x))^2 = (-6)^2 = 36$$
4. Resumen de resultados:
- \(\lim_{x \to c} [f(x)g(x)] = -3\)
- \(\lim_{x \to c} \frac{f(x)}{g(x)} = -12\)
- \(\lim_{x \to c} [f(x) + 2g(x)] = -5\)
- \(\lim_{x \to c} [f(x)]^2 = 36\)
