Answer:

a. square root

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
