1.The Question
The function f(x)=
x2/x if (x≠0)
0 if(x=0)
The book (one of those AP prep guides with solutions) says that it is continuous everywhere, to note that x2/x if x≠0 and lim(x->0) f = 0.
Why was I wrong?
Thanks in advance.

The Attempt at a Solution
I thought this had a removable discontinuity at x=0, because the function s2/x is not defined at x=0, and the expression can be reduced to x.The book (one of those AP prep guides with solutions) says that it is continuous everywhere, to note that x2/x if x≠0 and lim(x->0) f = 0.
