$f (x) = | x - 1 |$ , $g (x) = \frac{1}{x}$

Step 1

Set up the composite result function.

$f (g (x))$

Step 2

Evaluate $f (\frac{1}{x})$ by substituting in the value of $g$ into $f$ .

$f (\frac{1}{x}) = | (\frac{1}{x}) - 1 |$

Step 3

Remove parentheses.

$f (\frac{1}{x}) = | \frac{1}{x} - 1 |$
