Practice 1: $$( \sqrt{cos(x)}.cos(200x) + \sqrt{\left|x\right|}-0.7).(4-x^2)^{0.01}, \sqrt{9-x^2} , -\sqrt{9-x^2}$$

Practice 2: $$\,\,\,\, if \,\,\, g(x) \leq f(x) \leq h(x) \,\,\,\,\,  and  \,\,\,\,\,   \lim_{x \to a} g(x) = \lim_{x \to a} h(x) = L   \,\,\,\,\,  then  \,\,\,\,\,  \lim_{x \to a} f(x) = L \,\,\,\,$$
