Explain the meaning of each of the following. $($a$)\underset{x-2}{lim}f(x)=$ The values of $f(x)$ can be made arbitrarily large by taking $x$ sufficiently close to $($but not equal to$)-2.$ The values of $f(x)$ can be made arbitrarily close to $0$ by taking $x$ sufficiently close to $($but not equal to$)-2.$ The values of $f(x)$ can be made arbitrarily close to $-2$ by taking $x$ sufficiently large. $f(-2)=($b$)\underset{x{6}^{+}}{lim}f(x)=-$ The values of $f(x)$ can be made negative with arbitrarily large absolute values by taking $x$
