Continuity of a function

A function g(x) is said to be continuous at x0 if the limit of g(x) as x approaches x0 exists and equals g(x0). In simpler terms, a function is continuous at a point if its graph has no breaks or jumps at that point.

Limit of a function

If the limit of f(x) as x approaches x0 exists and equals L, we write: lim x→x0 f(x) = L. This means that as x gets closer and closer to x0 (but not equal to x0), the value of f(x) gets closer and closer to L.

Limit of the quotient of functions

If lim x→x0 f(x) = L and lim x→x0 g(x) = M (where M ≠ 0), then lim x→x0 [f(x)/g(x)] = L/M. This means that the limit of the quotient of two functions is equal to the quotient of their individual limits, assuming the denominator's limit is not zero.
