Find g(f(x)) f(x)=9x-4 , g(x)=(x+9)/4

$f (x) = 9 x - 4$ , $g (x) = \frac{x + 9}{4}$

Step 1

Set up the composite result function.

$g (f (x))$

Step 2

Evaluate $g (9 x - 4)$ by substituting in the value of $f$ into $g$ .

$g (9 x - 4) = \frac{(9 x - 4) + 9}{4}$

Step 3

Add $- 4$ and $9$ .

$g (9 x - 4) = \frac{9 x + 5}{4}$
