SUMMARY
The discussion centers on identifying discontinuities in the function F(X) = (X^2 - 2x + 1)^(1/3) over the interval [-4, 4]. Participants emphasize the importance of correctly graphing the function to locate points of non-differentiability. The confusion arises from the interpretation of the interval endpoints and whether the graph must touch these points to be considered continuous. Ultimately, the key takeaway is that a function can be continuous on an interval even if it does not touch the endpoints.
