Pre-Calculus - Where is a function continuous

[Ceaddamusic]

for the (-5, 2) i thought the 2 was suppose to be a bracket because the hole was closed indicating what i thought was not including 2. can you explain to me how you go your answer

[escapefromreality]

I have a question can we cut the function 2:20 min and say that it is continuous in some points?

[mathhelpp]

on 3:40, you said it is continuous on (2, ∞), and not [2, ∞). Can you please explain why?

[quayzahr]

What is the difference between using parentheses and brackets?

[ch]

What if you fold the paper to make them continuous

[mikeboon]

Did you forget to use proper interval notation or is there a special notation regarding continuity?

[mathhelpp]

What if the point was on (3, 2), and not (2, 2), would it be continuous on [3, ∞)?
