THE SET OF A FUNCTION IS LIMITED BY ITS DOMAIN
que quieres decir con "o conjunto da função"?
{x:x ≤ |-1|}
talvez você quer dizer: como \(-1\leq x\leq 1\) depois \[\large -1\leq-x\leq 1 \] e \[\large 0\leq x^2\leq 1 \] então \[\large -1\leq x^2-x\leq 1\]
sugiro postar em inglês, nem sempre vai ter alguém online que saiba português
