Sometimes a function:
The inverse function of y=x^2 is y=+/-sqrt(x), because remember the negative square of something is the same as the positive square of it.
y=+/-sqrt(x) fails the Vertical line test.
Inverses are only one to one if the original function is a bijection

Answer:

  See below

Step-by-step explanation:

The solution choices all agree that x = 1±√2. The second equation tells you ...

  y = ±2√(x+2)

so the sign of the √2 term in x is the same as the sign of the √2 term in y. The answer choices circled in red are the ones that meet this requirement.
