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
2 answers:
Answer:
C) Casey is incorrect because more than one student can have the same GPA.
Step-by-step explanation:
Casey states that there exists a function if we have,
Input = Student's GPA
Output = Student's name
Now, a function is a relation where for each value of 'x', the value of 'y' is unique.
From the given statement, we have that,
<em>A function exists if corresponding to every GPA, there exists only one student, which cannot be true.</em>
There can be more than one students having the same GPA.
Thus, the correct option is,
C) Casey is incorrect because more than one student can have the same GPA.
