Question
Evaluate each function at the given values of the independent variable and simplify.$$f(x)=\frac{x}{|x|}$$a. $f(6)$b. $f(-6)$c. $f\left(r^{2}\right)$
Step 1
This function is defined for all \( x \neq 0 \). The absolute value function \( |x| \) returns the non-negative value of \( x \). Therefore, \( f(x) \) will be 1 if \( x > 0 \), -1 if \( x < 0 \), and undefined if \( x = 0 \). Show more…
