Answer:
(x) = 4x + 48
Step-by-step explanation:
let y = f(x) and rearrange making x the subject, that is
y = 
x - 12 ( multiply through bt 4 to clear the fraction )
4y = x - 48 ( add 48 to both sides )
4y + 48 = x
Change t back into terms of x with x = (x)
(x) = 4x + 48
Answer:
y = 4x - 48
Step-by-step explanation:
y = 1/4 x - 12
x = 1/4 y - 12
4x = y - 48
y = 4x - 48
