A function [math] is said to have a removable discontinuity at [math] if:
1. [math] is either not defined or not continuous at [math].
2. [math] could either be defined or redefined so that the new function is continuous at [math].


Let [math].
Show that [math] has a removable discontinuity at [math] and determine the value for [math] that would make [math] continuous at [math].
Need to redefine [math] .
