Using the definition of a function, it is found that graph A does not represent a function.
---------------------------------
- The definition of a function is that one value of the output is attributed to each value of the input.
- If a value of the input is related to more than one output, it will not be a function.
- In a graph, the input is x and the output is y.
- Looking at the graphs given, it can be seen that in graph A, for values of [tex]x > 0[/tex], there are 2 values of y, that is, two outputs are mapped to one input, which means that it is not a function.
