For what value of mc009-1 is the function one-to-one?
exis [7]

Using the concept of an one-to-one function, it will be one-to-one for c = 13.

<h3>What is an one-to-one function?</h3>

A function is said to be one-to-one if each output is mapped to only one input.

In this problem, outputs 2, 5 and 11 have already been matched to inputs 1, 3 and 5, respectively, hence the output for input 6 has to be c = 13 for a one-to-one function.
