WebJul 5, 2024 · To be continuous at a point (say x=0), the limit as x approaches 0 must equal to the actual function evaluated at 0. The function f(x)=1/x is undefined at 0, since 1/0 is undefined. Therefore there is no way that the f(0) = lim x->0 f(x). WebOct 22, 2016 · This video teaches students how to determine if a piecewise function is continuous at a point.
