Domain refers to the set of possible input values (x-values) for a function.
Range refers to the set of possible output values (y-values) for a function.
A function is defined as a relationship where each input is linked to exactly one output.

Card 1
- Domain: [-6, 6]
- Range: [0, 6]
- Classification: Function (pass test of uniqueness)
Card 2
- Domain: [-7, 5)
- Range: [-3, 1)
- Classification: Function (valid mapping from inputs to outputs)
Card 3
- Domain: x = -5 (single input)
- Range: -2 < y < 6 (multiple outputs for a single input)
- Classification: Not a function (fails uniqueness criteria)
Card 4
- Domain: [-4, 4]
- Range: [-4, 4]
- Classification: Not a function (multiple outputs for some inputs)
Card 5
- Domain: [0, Infinity) (all non-negative inputs)
- Range: (-Infinity, Infinity) (outputs could be any real number)
- Classification: Not a function (fails uniqueness)
Card 6
- Domain: x > 0 (only positive inputs)
- Range: y = 4 (single output for all inputs)
- Classification: Function (consistent mapping)
Card 7
- Domain: (-3, 5]
- Range: [-1] (only one output)
- Classification: Function (each input gives one output)
Card 8
- Domain: [-4, 2]
- Range: [-2, 4]
- Classification: Function (valid relationship)
Card 9
- Domain: (-3, 4)
- Range: [0, 5)
- Classification: Function (unique outputs for each input)
