Answer:

first option

Explanation:

Given

y = 2(x - 3)² + 1

Rearrange making x the subject

Subtract 1 from both sides

y - 1 = 2(x - 3)² ( divide both sides by 2 )


\sqrt{(y-1)/(2) } = (x - 3)² ( take the square root of both sides )

±
\sqrt{(y-1)/(2) } = x - 3 ( add 3 to both sides )

±
\sqrt{(y-1)/(2) } + 3 = x

Change y into terms of x with x being the inverse, that is


f^(-1) (x) = ±
\sqrt{(x-1)/(2) } + 3
