The set of all possible output values (y-values) for a function.

Use brackets [ ] for inclusive endpoints and parentheses ( ) for exclusive endpoints.

All real numbers, expressed as (-∞, ∞).

All real numbers, expressed as (-∞, ∞).

All real numbers except x = 2, expressed as (-∞, 2) U (2, ∞).

All real numbers y such that y ≥ 0, expressed as [0, ∞).

All real numbers x such that x ≥ 1, expressed as [1, ∞).

All real numbers y such that y ≥ 0, expressed as [0, ∞).

Identify the values of x that make the function undefined (like division by zero) and exclude them.
