📚 Grade 12 Math: Exercise 2.2 - Limits, Continuity & Discontinuity Solutions 📚

In this video, I’ve solved Exercise 2.2 from Unit 02: Limit, Continuity, and Derivative for Grade 12/2nd Year students. This exercise covers:
✔ Determining discontinuities in functions (Problems 1-8)
✔ Checking continuity over intervals (Problems 9-14)
✔ Finding values of m and n for piecewise continuity (Problems 15-18)
✔ Proofs of solutions in intervals (Problem 19)
✔ Discontinuity of Dirichlet function (Problem 20)
