No, the function f does not necessarily have to be defined at x=t. The limit of a function as x approaches a certain value only describes the behavior of the function as it gets close to that value, not at the value itself. There are many cases where a function can have a limit at a certain point but is not defined at that point. For example, the function f(x) = (x^2 - 1) / (x - 1) has a limit of 2 as x approaches 1, even though the function is not defined at x = 1.
