Answer:


\huge\boxed{D) \ f^(-1)(x) = (x-3)^2+2}

Explanation:


f(x) = √(x-2) + 3

Replace f(x) by y


y = √(x-2) + 3

Interchange x and y


x = √(y-2) + 3

Solve for y


x = √(y-2) + 3

Subtracting 3 to both sides


x - 3 = √(y-2)

Taking square on both sides


(x-3)^2 = y-2

Adding 2 to both sides


y = (x-3)^2 + 2

Replace
y = f^(-1)(x)


f^(-1)(x) = (x-3)^2+2
