Start by solving for x:
y = x^2 − 36
x^2 = y + 36
x = ±√(y + 36)

As an inverse relation: x = ±√(y + 36). To write an inverse function, you must restrict the original domain:

- If original domain is x ≥ 0, the inverse is f⁻¹(x) = √(x + 36), domain x ≥ −36.
- If original domain is x ≤ 0, the inverse is f⁻¹(x) = −√(x + 36), domain x ≥ −36.

(If no domain restriction is given, the inverse is not a single-valued function.)
