Draw the graph of the function f(x)=(x2-4)/(x+2)

Dear student

$$\begin{gathered} \mathrm{f}\left(\mathrm{x}\right)=\frac{{\mathrm{x}}^2-4}{\mathrm{x}+2} \\ \mathrm{f}\left(\mathrm{x}\right)=\frac{\left(\mathrm{x}-2\right)\left(\mathrm{x}+2\right)}{\mathrm{x}+2}=\mathrm{x}-2 \\ \mathrm{i}.\mathrm{e}, \mathrm{y}=\mathrm{x}-2 \end{gathered}$$
