Answer:
C.3
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


Where k=proportionality constant
Substitute the given values then, we get



Substitute the value of k then, we get

Substitute the value of w=2
Then, we get


Hence, option C is true.
