$m (x) = \frac{x + 5}{x - 1}$ $N (x) = x - 3$

Step 1

Set up the composite result function.

$m (N (x))$

Step 2

Evaluate $m (x - 3)$ by substituting in the value of $N$ into $m$ .

$m (x - 3) = \frac{(x - 3) + 5}{(x - 3) - 1}$

Step 3

Add $- 3$ and $5$ .

$m (x - 3) = \frac{x + 2}{x - 3 - 1}$

Step 4

Subtract $1$ from $- 3$ .

$m (x - 3) = \frac{x + 2}{x - 4}$
