Question

(will give brainliest) In Exercises 8 and 9, determine whether the statement uses the word function in a way that is mathematically correct. Explain your reasoning.
8. A function pairs each teacher with 30 students.
9. The cost of mailing the package is a function of the weight of the package.

Answer 1

The true statements are:

• 8. The word function is not mathematical correct
• 9. The word function is  mathematical correct

How to determine if the word "function" is correct

All functions are relations; however, not all relations are functions

For a relation to be a function, then the relation must be one to one or many to one.

The relation that pairs each teacher with 30 students is not a function.

This is so because, it represents a one-to-many relationship

However, the relation of the cost and weight of a package is a function.

This is so because, it represents a many-to-one relationship, and several weights can have the same cost
