A function is continuous if it is unbroken fro all values of x. T he formal definition states that f(x) is continuous if the limit as f(x) approaches a is equal to that of f(a).

It is also important to remember that the lim of f(a) exists iff f(x) approaching a from the left is equal to the lim f(x) as x approaches a from the right.

This can also be defined:
