In their definitions, the value of the function at the point of discontinuity varies from one author to another. Why is this the case?
Also, the authors draw a vertical line at the point of discontinuity. Isn't this incorrect? (surely, the function cannot be drawn as multivalued if it is single-valued in the definition?)
I am also wondering if the function can have multiple values at the point of discontinuity.
Thanks in advance!
