Answer:

C.3

Step-by-step explanation:

We are given that

f(w) varies inversely with w.

f(w)=0.75 when w=8

We have to find the value of f(w) when w=2

According to question

f(w)\propto\frac{1}{w}

f(w)=\frac{k}{w}

Where k=proportionality constant

Substitute the given values then, we get

0.75=\frac{k}{8}

k=0.75\times 8

k=6

Substitute the value of k then, we get

f(w)=\frac{6}{w}

Substitute the value of w=2

Then, we get

f(w)=\frac{6}{2}=3

f(w)=3

Hence, option C is true.
