To decide:who’s statement is correct and give explanation.
Answer to Problem 4CFU
Kesisha is correct. A relation can have more than one element in the range for a single element in the domain and function is a relation whose each element of the domain is paired with exactly one element in the range.
Explanation of Solution
Given information:
Kesisha statement is all functions are relations but not all relations are functions. Kevin’s statement is all relations are functions but not all functions are relations.
A relation whose each element of the domain is paired with exactly one element in the range is called a function. Whereas a relation can have more than one element in the range for a single element in the domain.
Since all functions are relation but all relations are not functions. Hence, Kesisha’s statement is true.
