1. It is a rule that relates values from a set to second set of value.?
Answer (1)
Answer:A relation is a rule that associates elements from one set (the domain) to elements in another set (the range). A function is a specific type of relation where each element in the domain is related to only one element in the range. Step-by-step explanation:Relation:A relation is a broad concept that defines a connection or correspondence between elements of two sets. It can be represented in various ways, including ordered pairs, tables, graphs, or mapping diagrams. Function:A function is a special type of relation that adheres to a stricter rule: for every input (element in the domain), there must be exactly one output (element in the range). Example:Consider a set of students and a set of their grades. A relation could be "is enrolled in," where a student is associated with one or more courses. A function could be "earns a grade of," where each student receives only one grade in a particular course. Key Difference:While all functions are relations, not all relations are functions. A relation might map one element in the domain to multiple elements in the range, which would not be a function.
