Important Questions from Limits And Continuity
The function \( f(x) = \frac{1}{x} \) is not defined at which point?
Show answer
x = 0
Division by zero is undefined, so \( f(x) = \frac{1}{x} \) is not defined at \( x = 0 \).
What is \( \lim_{x \to 2} (x^2 - 4) \)?
Which of the following is an open interval?
Show answer
(0, 5)
An open interval excludes both endpoints and is denoted by parentheses.
