Consider the picewise funcion uarr$(x)$

$f(x)=\{\begin{array}{ccc}g(x)& if& |x|n\\ h(x)& if& |x|>n\end{array}$

where

$g(x)=8tan(\frac{x}{4})$

$h(x)=4|x-n|$

$n=(4)(43)$

How many points of discontinuities of

the function $f(x)$ on the interval $-(n+1)xn+1$

$($ see $53$ and $58$ sec $2\mathrm{.}4)$
