Within the lecture on session 1, it is stated that
Y0 = 1/x0 (Y subzero One over x subzero). Why is that? I understood that Yo = f(1/x0).
Also, in the example f(x) = 1/x, seems a statement rather that a truth.

Sorry, folks.  It is Calculus 1, First Class. Around minute 17:32. The statement is Yo = 1/xo.  It is read, Y subzero = 1/X subzero).  The question is why is this true?
