This question practices checking points against a quadratic inequality y ≤ x² - 1.
\( \text{Which of the following points satisfy the inequality } y \leq x^2 - 1? \)
Select all correct options:
Check each point carefully and eliminate any points that do not satisfy the inequality.
Substitute x and y of each point into the inequality. Only points satisfying y ≤ x² - 1 are correct.
