Question

Does the relationship show a function?

Input

2
4
3
Output

20

30

40

Answer 1

No, the relationship does not show a function. A function is a relationship between an input and an output, where each input has a unique output. However, in this case, the input values 2, 4, and 3 all have multiple output values: 20, 30, and 40, respectively. Therefore, it does not conform to the definition of a function.
