Question
If $|f|$ is continuous at a point, then is it true that $f$ is also continuous at this point?
Step 1
Step 1: Recall that the absolute value function $|x|$ is defined as follows: $|x| = \begin{cases} x & \text{if } x \geq 0 \\ -x & \text{if } x < 0 \end{cases}$ Show more…

Determine whether the converse of exercise 49 is true. That is, if $|f(x)|$ is continuous at $x=a$, is it necessarily true that $f(x)$ must be continuous at $x=a ?$

Determine whether the converse of exercise 65 is true. That is, if $|f(x)|$ is continuous at $x=a,$ is it necessarily true that $f(x)$ must be continuous at $x=a ?$
Continuity and its Consequences
An assertion is made about a function $f$ that is defined on a closed, bounded interval. If the statement is true, explain why. Otherwise, sketch a function $f$ that shows it is false. (Note: $|f|$ is defined by $|f|(x)=|f(x)| .)$ If $f$ is continuous, then $|f|$ is continuous.
