Limit and Removable Discontinuity

Question

Which of the following equations defines a function $$f(x)$$ that has a removable discontinuity at $$x = -2$$ and for which $$\lim_{x 	o -2} f(x) = 1$$? (Do not use a calculator.)

Accepted Answer

$$\frac{2*\sqrt{2}\cdot(\sqrt{x+4}-\sqrt{2})}{x+2}$$

Answer

$$\frac{2*(\sqrt{x+4}-\sqrt{2})}{x+2}$$

Answer

$$\frac{2*\sqrt{2}\cdot(\sqrt{x+4}+\sqrt{2})}{x+2}$$

Answer

$$\frac{\sqrt{x+4}-\sqrt{2}}{x+2}$$
