Vamos analisar cada limite dado que: \[ \lim_{x \to a} f(x) = -3, \quad \lim_{x \to a} g(x) = 0, \quad \lim_{x \to a} h(x) = 8 \] a) \(\lim_{x \to a} [f(x) + h(x)] = \lim f(x) + \lim h(x) = -3 + 8 = 5\) b) \(\lim_{x \to a} \frac{g(x)}{f(x)} = \frac{\lim g(x)}{\lim f(x)} = \frac{0}{-3} = 0\) c) \(\lim_{x \to a} \frac{2 f(x)}{h(x) - f(x)} = \frac{2 \cdot \lim f(x)}{\lim h(x) - \lim f(x)} = \frac{2 \cdot (-3)}{8 - (-3)} = \frac{-6}{11} = -\frac{6}{11}\) Respostas: a) 5 b) 0 c) \(-\frac{6}{11}\)
