Z varies inversely as w ⇒ z*w=k
when z=7 and w=8 ⇒ 7*8=56=k

when w=14 ⇒ z*14=56
⇒z=56/14
⇒ z=4

Answer:

$f^{-1}$ (x) = $\frac{x}{4\\}$

Step-by-step explanation:

Let y = f(x) and rearrange making x the subject

y = 4x ( divide both sides by 4 )

x = $\frac{y}{4}$

Change y back into terms of x

$f^{-1}$ (x) = $\frac{x}{4\\}$
