Answer 1

9514 1404 393

Answer:

  a.  square root

Step-by-step explanation:

For function f(x) = x², the inverse function is found by solving ...

  x = f(y)

  x = y²

If we take the square root of both sides of this equation, we get ...

  √x = y

That is, the inverse of the quadratic function f(x) is ...

  f⁻¹(x) = √x . . . . . square root
