c.

Yes, it is a function. Each numerical grade corresponds to one letter grade

Explanation:

It is given that:

The letter grade in this course is a function of your numerical grade.

i.e. corresponding to a numerical grade a letter grade is assigned.

Hence, corresponding to one numerical grade a single letter grade will be given.

This means that each element will have a unique image.

Hence, the given situation describes a function.

Hence, option C is true.

c.

Yes, it is a function. Each numerical grade corresponds to one letter grade
