$f (x) = 3 x$ $y (x) = \frac{2}{x}$ $z (x) = \sqrt{x}$

Step 1

Set up the composite result function.

$f (y (x))$

Step 2

Evaluate $f (\frac{2}{x})$ by substituting in the value of $y$ into $f$ .

$f (\frac{2}{x}) = 3 (\frac{2}{x})$

Step 3

Multiply $3 (\frac{2}{x})$ .

Step 3.1

Combine $3$ and $\frac{2}{x}$ .

$f (\frac{2}{x}) = \frac{3 \cdot 2}{x}$

Step 3.2

Multiply $3$ by $2$ .

$f (\frac{2}{x}) = \frac{6}{x}$
