“Bisexual function” domain problem on a number line

{
  "input": {
    "prompt": " Illustration of a number line with the negative side shaded or faded out and a √x curve starting at x=0 on a coordinate grid. Add a small annotation like “Defined only for x ≥ 0 (in reals)” to underline the joke about “erasing half the number line.” Keep it respectful and clearly aimed at the metaphor, not at bisexuality."
