Find g(f(x)) f(x)=9x and g(x)=x/9

$f (x) = 9 x$ and $g (x) = \frac{x}{9}$

Set up the composite result function.

$g (f (x))$

Evaluate $g (9 x)$ by substituting in the value of $f$ into $g$ .

$g (9 x) = \frac{9 x}{9}$

Cancel the common factor of $9$ .

Cancel the common factor.

$g (9 x) = \frac{9 x}{9}$

Divide $x$ by $1$ .

$g (9 x) = x$
