"The given expression is
2(x - 2)² = 8(7 + y)
Rewrite the expression as follows:
7 + y = (2/8)(x-2)² = (1/4)(x-2)²
y = (1/4)(x-2)² - 7
To find the inverse, switch x and y, and solve for y.
x = (1/4)(y-2)² - 7
Multiply through by 4.
4x = (y-2)² - 28
(y-2)² = 4x + 28
y - 2 = √(4x + 28)
y = 2 +/- √(4x + 28)
This expression is the inverse of the given expression.
Therefore the answer is D."
