Question

Domain Range
8 4
0 0
1 0
7 3
Is this a function

Answer 1

To determine if the given set of pairs represents a function, we need to see if each input (or domain value) is associated with exactly one output (or range value).

In the pairs you've provided:
- Domain 8 → Range 4
- Domain 0 → Range 0
- Domain 1 → Range 0
- Domain 7 → Range 3

Here are the domain values:
- 8 maps to 4
- 0 maps to 0
- 1 maps to 0
- 7 maps to 3

Each domain value (8, 0, 1, 7) maps to a corresponding range value. However, the domain value 1 maps to the range value 0, while the domain value 0 also maps to the same range value 0. This means that multiple domain values can map to the same range value, which is allowed in a function.

Since every input (domain value) corresponds to one and only one output (range value), this set does indeed represent a function.
