Find g(f(x)) f(x)=2x-9 , g(x)=(x+2)/9

$f (x) = 2 x - 9$ , $g (x) = \frac{x + 2}{9}$

Step 1

Set up the composite result function.

$g (f (x))$

Step 2

Evaluate $g (2 x - 9)$ by substituting in the value of $f$ into $g$ .

$g (2 x - 9) = \frac{(2 x - 9) + 2}{9}$

Step 3

Add $- 9$ and $2$ .

$g (2 x - 9) = \frac{2 x - 7}{9}$
