I don't see the function — could you post the formula? I need it to pick the correct domain.

Meanwhile, here are quick rules to help you decide which of your three choices applies once you give the function:

- If the expression is a polynomial (e.g. x^2 + 3x − 5) → domain = all real numbers.
- If the expression is a rational function with x in the denominator (e.g. 1/x or (x+1)/(x−2)) → exclude values that make the denominator 0 (e.g. all real numbers except 0 for 1/x).
- If the expression involves ln(x) or any logarithm with base >1 → argument must be > 0, so domain is x > 0.
- If it involves an even root (e.g. sqrt(x) or 4th root) → radicand must be ≥ 0 (domain x ≥ 0, not x > 0).

Post the specific function and I’ll identify the correct domain from your choices.
