Worth 50 identify the errors made in finding the inverse of y = x^2 + 12x.
x=y^2+12x
y^2=x-12x
y^2=-11x
y=√-11x, for x ≥0
describe the 3 errors

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

y =

So inverse will be y =

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

square root of 36/6 = 2.449489743

square root of 16/6 = 1.632993162

square root of 6 = 2.449489743

the answer is square root of 16/6 because the square root of 36/6 is the same answer as square root of 6 = 2.449489743
