Answer:

The constant of proportionality is 2.

Explanation:

Given :
f(x)=3(x+4)-x-12

To find = Constant of proportionality = k= ?

Solution :


f(x)=3x+12-x-12


f(x)=2x


f(x)=k* x

Direct proportion is represented by :
(f(x)\propto x)

On comparing , we get:

k = 2

The constant of proportionality is 2.
