Later on when I do math I'll put T of x which is my name (tracy) instead of f(x) :))

Hi patrick, I don't understand what you meant by a "hole in the graph". Isn't the answer of zero divided by zero undefined? If so, how can it not be an asymptote when the answers of a numerator divided by zero is also similarly undefined?

[patrickJMT]

@MrRzguitario well, the calculus reason is because the limit exists but it is not continuous. it is only zero/zero at that specific point. what happens if you plug in a number close to it, but not equal to the offending value?

thanksss a lot patrick.now i can skip my class and will just watch your videos :)

[patrickJMT]

@malotyxz go to class. : ) and watch my videos ; )

I've learned more from you in the past 30 minutes than I have in the past three months in my college Algebra class.

I learned the P in P(x) is for Patrick

Thank you so much!

Thanks Patrick! You saved me the extra time I'd spend pondering over these problems!

thank you so much! you made it soo simple=)

This really helps me do my advanced math project and study for finals as well!
