Question

find the domain range of f(x)=lx-4l

Answer 1

Answer:

The domain is R and range is $[0,\infty)$

Step-by-step explanation:

      $f(x)=|x-4|$

Since absolute value of any real number exist so $|x-4|$ is defined for all real $x$

$\Rightarrow$ Domain is $\text{R}$

And since absolute value is always greater than or equal to zero

$\Rightarrow$ Range is $[0,\infty)$
