Math Analysis HL Unit 6 Video 3: Estimating limits graphically classwork problems 1-7 (Chapter 4.1A)

@IBMathwithGary In this video, Gary summarizes the results of our investigation into limits and continuity, and then solves classwork problems 1 - 7 in Chapter 4.1A of the Oxford textbook. These problems involve estimating limits at a point graphically. There are three conditions that must exist for a function to be continuous (1) the function must exist at x = a (2) the limit of the function at x = a must exist (3) the limit of the function at x = a must equal the function value at x=a The limit of a function at x=a, however, is independent of the function value at x = a. This happens when there is a removable discontinuity. Ditch AI, get help from Gary!
