$g (x) = \sqrt{x - 1}$ , $g (x) = \sqrt{x - 1}$

Step 1

Set up the composite result function.

$g (g (g (g (x))))$

Step 2

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

$g (\sqrt{x - 1}) = \sqrt{(\sqrt{x - 1}) - 1}$

Step 3

Remove parentheses.

$g (\sqrt{x - 1}) = \sqrt{\sqrt{x - 1} - 1}$
