$f (x) = 4 x$ and $g (x) = \frac{x}{4}$

Step 1

Set up the composite result function.

$f (g (x))$

Step 2

Evaluate $f (\frac{x}{4})$ by substituting in the value of $g$ into $f$ .

$f (\frac{x}{4}) = 4 (\frac{x}{4})$

Step 3

Cancel the common factor of $4$ .

Step 3.1

Cancel the common factor.

$f (\frac{x}{4}) = 4 (\frac{x}{4})$

Step 3.2

Rewrite the expression.

$f (\frac{x}{4}) = x$
