Use the given graphs of the function $f$ (left, in blue) and $g$ (right, in red) to find the following limits:

1. $\displaystyle \lim_{x \to 1}[f(x)+g(x)] =$ help (limits)

2. $\displaystyle \lim_{x \to 2}[f(x)+g(x)] =$

3. $\displaystyle \lim_{x \to 0}f(x)g(x) =$

4. $\displaystyle \lim_{x \to 0}\frac{f(x)}{g(x)} =$

5. $\displaystyle \lim_{x \to -1}\sqrt{3+f(x)} =$
