Answer:
(x) =
x + 8
Step-by-step explanation:
let y = f(x) and rearrange making x the subject, that is
y = 9(x - 8) ← divide both sides by 9
= x - 8 ( add 8 to both sides )
+ 8 = x
Change y back into terms of x with x =
(x) , thus
(x) =
x + 8
Answer:
x = ±√37/9
Step-by-step explanation:

√(x²) = √(37/81)
x = ± √(37)/√(81)
x = ± √37/9
