Another look on continuous functions.


The definition of Continous Functions may be a little hard to understand, so lets give it another look on how you can conclude that a function is continuous.

Sample Problem

Lets see the following function:
F(x) = 2x

Limit 2x = f(c)

This may sound really confusing for some people, but what it basically says is that:
“A function is continuous if you can draw its graph without taking the pen out of the paper”.

This may sound unsophisticated, and it really is, but when you find yourself in a situation that you can’t see if the function is continuous or not, this may help you.


Above you can see that the function A can be drawn without taking the pen out of the paper, while the second graph can not.
