Answer:
1st option
Step-by-step explanation:
let y = h(x) and rearrange making x the subject , that is
y = 6x - 6 ( add 6 to both sides )
y + 6 = 6x ( divide both sides by 6 )
[tex]\frac{y+6}{6}[/tex] = x
change y back into terms of x with x = [tex]h^{-1}[/tex] (x)
[tex]h^{-1}[/tex] (x) = [tex]\frac{x+6}{6}[/tex]
