Question

1. which of the following is not a characteristic of a function?

a. a graph passes the vertical line test
b. none of the answers
c. each input has exactly one output
d. multiple outputs can be assigned to one input

Explanation:

A function is defined such that each input has exactly one output, which is verified by the vertical line test for graphs. Option d directly contradicts this core definition, as it describes a relation that is not a function.

Answer:

d. Multiple outputs can be assigned to one input
