Answer 2

Using the concept of function, it is found that diagram C does not represent a function.

--------------------------

• In a function, each value of the input can be related to a single value of the output.

• In the diagram, from each value in the input, only one line can be exiting.
• If we look at diagrams A, B and D, each value of the input has only one respective value on the output, and thus, these diagrams are functions.
• At diagram C, the input 7 is mapped to outputs 8 and 12, that is, a single input mapped to 2 outputs, so it is not a function.
