Identify the errors made in finding the inverse of y = x2 + 12x.

The student did not switch both instances of  x  with  y. he should have written  x  =  y2  + 12y.he wrote only the principal square root instead of using the ± sign.the domain is incorrect. for the radicand to be greater than or equal to zero,  x  must be less than or equal to zero. it should be  x    0

check your answer. did you identify these three errors correctly?

the student did not switch both instances of x with y. he should have written x = y2 + 12y.

he wrote only the principal square root instead of using the ± sign.

the domain is incorrect. for the radicand to be greater than or equal to zero, x must be less than or equal to zero.
