$f (x) = x - 230$ ; $g (x) = 0.9 x$

Step 1

Set up the composite result function.

$g (f (x))$

Step 2

Evaluate $g (x - 230)$ by substituting in the value of $f$ into $g$ .

$g (x - 230) = 0.9 (x - 230)$

Step 3

Apply the distributive property.

$g (x - 230) = 0.9 x + 0.9 \cdot - 230$

Step 4

Multiply $0.9$ by $- 230$ .

$g (x - 230) = 0.9 x - 207$
