Question

Which of the following is the graph of a function?

Answer 1

Answer:

A

Step-by-step explanation:

Each domain value (x-value) of a function has exactly one range value (y-value).

A function can have two or more domain (x-value) having the same range (y-value)

Graph A shows the different domain value (x-values) having exactly one range value (y-value). No x-value has two different y-values.

Therefore, graph A is a function.
