Continuity Verification Example 1

This example demonstrates the verification of function continuity through graphical representation, showcasing continuous and discontinuous points of functions. Core mathematical concepts include continuity definitions, ε-δ language, unit circle, linear regression, and integer operations. Construction highlights involve GeoGebra commands/objects like Point, f, A, g, h, i, j, k, ε_1, δ_1, a, l, m, n, p, ε_2, q, r, XProber, P, fx, YProber. Suitable for high school and above learners to grasp continuity theory and practical applications.
