Verified step by step guidance1
Step 1: Understand the definition of a function in mathematics. A function is a relation between a set of inputs (domain) and a set of possible outputs (range) where each input is related to exactly one output.
Step 2: Analyze the options provided in the problem. Eliminate choices that do not align with the definition of a function.
Step 3: Option A, 'A method for solving systems of equations,' does not describe a function. It refers to a different mathematical process.
Step 4: Option B, 'A set of numbers arranged in ascending order,' describes an ordered set, not a function.
Step 5: Option D, 'A relation where each input has exactly one output,' matches the definition of a function. This is the correct answer.
