Math Problem Statement
Indicate whether the following statement is true or false. The function f(x) = |x| is continuous at every real number.
Solution
The statement is True. The function is indeed continuous at every real number. Absolute value functions do not have any breaks, jumps, or points of discontinuity. This continuity holds across all real numbers, including at , where there is a sharp corner but no discontinuity.
Would you like a detailed explanation on continuity or the concept of absolute value functions?
Here are some related questions to deepen your understanding:
- What does it mean for a function to be continuous at a point?
- How can you prove the continuity of a piecewise function?
- Are all absolute value functions continuous?
- What types of functions have points of discontinuity?
- How does continuity differ from differentiability at sharp points, such as for ?
Tip: A function is continuous if you can draw it without lifting your pencil, meaning it has no gaps, jumps, or breaks in its domain.
