Answer:

error is in step (1) x and y should be flipped.

Step-by-step explanation:

Steps to find inverse should be

y = x² + 12x

x = y² + 12y

x + 36 = y² + 12y +36

x + 36 = (y + 6)²

\sqrt{x+36}=(y+6)

y = (\sqrt{x+36}-6)

So inverse will be y = (\sqrt{x+36}-6)

Therefore, error is in step (1) x and y should be flipped.
