The value k that makes the piecewise function continous

The video tutorial explains the concept of discontinuity in a rational expression where X cannot equal zero. The teacher demonstrates how to simplify the expression by factoring out X, identifying the removable discontinuity, and evaluating the simplified expression. The tutorial also covers the graphical representation of the expression, highlighting the hole at X = 0 and explaining how to find the value that fills this hole.
