Find g(f(x)) f(x)=9x-8 , g(x)=(x+9)/8

$f (x) = 9 x - 8$ , $g (x) = \frac{x + 9}{8}$

Step 1

Set up the composite result function.

$g (f (x))$

Step 2

Evaluate $g (9 x - 8)$ by substituting in the value of $f$ into $g$ .

$g (9 x - 8) = \frac{(9 x - 8) + 9}{8}$

Step 3

Add $- 8$ and $9$ .

$g (9 x - 8) = \frac{9 x + 1}{8}$
