input: 2 = 20, 40

Question

4 = 40
3 = 30
is this a function

Answer 1

To determine if the given relation is a function, we need to check if each input (or "x" value) corresponds to exactly one output (or "y" value).

Let's analyze the pairs you've provided:

1. Input (2) maps to outputs 20 and 40.
2. Input (4) maps to 40.
3. Input (3) maps to 30.

For a relation to be considered a function, each input must map to exactly one output. In this case, the input 2 has two different outputs (20 and 40), which violates the definition of a function.

Therefore, the relation you provided is not a function.
