F x x + x-1 is continuous at
WebA discontinuity is a point at which a mathematical function is not continuous. Given a one-variable, real-valued function y= f (x) y = f ( x), there are many discontinuities that can occur. The simplest type is called a removable discontinuity. Informally, the graph has a "hole" that can be "plugged."
