Question

Casey says that a function exists if the input is a student's GPA and the output is the student's name. Is Casey incorrect? Why or why not?

Answer 1

Casey is incorrect because more than one student can have the same GPA or name. Hope I helped! (:

Answer 2

Using the restriction for the existence of a function, it is found that Casey is incorrect, as two different students can have the same GPA.

The restriction for the existence of a function is:

• For each input, there can be only one respective output.

Considering the input as the student's GPA and the output as the student's name, multiple different students can have the same GPA, that is, one input could have multiple outputs, meaning that a function does not exist, and Casey is incorrect.
