Continuity of a Function at a Point

This animation explains what it means for a function to be continuous at a point, using the formal limit definition lim x→x0 f(x) = f(x0). It walks through the three conditions required for continuity, contrasts continuous and discontinuous graphs, and works a step-by-step example checking continuity at a given point. Clean slides and clear notation make it suitable for 2Bac students studying limits and continuity in preparation for calculus topics like derivatives.
