Question

f(x)=3(x+4)-x-12f ( x ) = 3 ( x + 4 ) − x − 12 represents a direct proportionality. Find the constant of proportionality, kk .

Answer 1

Answer:

The constant of proportionality is 2.

Step-by-step explanation:

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

To find = Constant of proportionality = k= ?

Solution :

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

$f(x)=2x$

$f(x)=k\times x$

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

On comparing , we get:

k = 2

The constant of proportionality is 2.
