Although Lim f (x) exists, what does Lim f (x) ≠ f (x0) mean Although LIM (x → x0) f (x) exists, what does Lim f (x) ≠ f (x0) mean What is the specific situation? Can you give an example of a function that meets the conditions~ Thank you~

"LIM (x → x0) f (x) exists, but Lim f (x) ≠ f (x0)" means that function f (x) has limit at x0, but its limit at x0 is not equal to the function value at x0. For example, when x ≠ 0, function f (x) = 1. When x = 0, function f (x) = 0. ∵ LIM (x - > 0) f (x) = 1, and f (0) = 0 ∵ LIM (x - > 0) f (x).... "
