Rodney Mason · Answer 1

f (x) = - 3x + 4

Step-by-step explanation:

Given

9x + 3y = 12

We require to rearrange expressing y in terms of x

Subtract 9x from both sides

3y = - 9x + 12 (divide all terms by 3)

y = - 3x + 4

Expressed in functional notation by replacing y by f (x), that is

f (x) = - 3x + 4
