Questions on Limits and Continuity

This example demonstrates the concepts of limits and continuity of functions at a point through interactive graphics. Key math concepts include limits, continuity, inequalities, and linear regression. Construction highlights involve using Textfield for input boxes, Intersect for intersection points, with objects a, b, f, inputBox1, A, B, C, D, c. Suitable for high school and above students to understand the geometric meaning and calculation methods of limits and continuity.
