Question 1
What does it mean for a function to be continuous at a point $x = c$?
Question 2
Which condition is not required for continuity at a point?
Question 3
If $\lim_{x \to 2} f(x) = 5$ and $f(2) = 5$, what can be concluded about $f$ at $x = 2$?
Question 4
A function has a hole at $x = 4$, but the limit as $x \to 4$ exists. What is most likely true?
Question 5
Which graph feature most directly indicates continuity at a point?
