Which term describes the largest value a function attains over its domain?

• A. Maximum Value
• B. Global Maximum
• C. Extrema
• D. Ceiling

Answer: (B)

The largest value a function attains when you look at every input in its domain is called the global maximum. It’s the highest y-value the function reaches across the whole domain, not just near a particular point. If several inputs give the same top value, that value remains the global maximum. The term global maximum is the precise way to express “largest value over the entire domain,” whereas extrema is a broader term that includes local highs and lows, and a ceiling is unrelated.
