Verified step by step guidance1
Step 1: Understand the definition of a function in mathematics. A function is a relation where each input from a given set (domain) is assigned exactly one output in another set (range).
Step 2: Analyze the options provided in the problem. Look for the one that aligns with the definition of a function.
Step 3: Eliminate options that do not match the definition. For example, 'a set of numbers arranged in ascending order' does not describe a function, as it does not involve input-output relationships.
Step 4: Similarly, 'a collection of activities and elements organized to accomplish a goal' and 'a process of multiplying two numbers together' do not align with the mathematical definition of a function.
Step 5: Identify the correct option: 'A relation that assigns exactly one output to each input from a given set,' as it matches the precise definition of a function in mathematics.
