Answer:

x = y² + 12x

y² = x - 12

y² = -11x.

Step-by-step explanation:

We need to find the inverse of the given function , which is ,

\rm\implies y = x^2 + 12x

Step 1 : <u>Interchange</u><u> </u><u>x </u><u>and </u><u>y </u><u>:</u><u>-</u><u> </u>

\rm\implies x = y^2 + 12y

But according to the steps given in the Question , in very first step in 12x , x is not replaced by y . After which , the steps go wrong in the question .

<u>The </u><u>3 </u><u>errors </u><u>:</u><u>-</u><u> </u>
