Question

1. based on the table, determine if the relation between the students & the number of books they read is a function. explain your reasoning.

student	books read
bob	3
cho	5
dana	2

Explanation:

A relation is a function if each input (student) has exactly one output (number of books read). In this table, every student is paired with one unique number of books; no student is mapped to more than one value. Note that multiple inputs can map to the same output (Alice and Cho both read 5 books) and this does not violate the definition of a function.

Answer:

Yes, the relation is a function. Each student (input) is associated with exactly one number of books read (output), which satisfies the definition of a function.
