# Understanding Negative Results: The Mathematical Interpretation of g(2) = 2 - 4 = -2 When students first encounter expressions like g(2) = 2 - 4 = -2, they often seek a simple explanation—why is the result negative? In mathematics, negative numbers are not merely abstract concepts; they represent real-world relationships, balances, inversions, and geometric interpretations. This article dives deep into the equation g(2) = 2 - 4 = -2, exploring its significance, applications, and how negative values shape our understanding of functions, equations, and real-life scenarios. ## What Does g(2) Represent? The Meaning Behind the Input Value In functional terms, g(2) means the output of the function g when the input is 2. When we write g(2) = 2 - 4, we’re evaluating g at a specific point—here, x = 2—and revealing that g(2) equals -2 because 2 minus 4 = -2. This notation illustrates a direct substitution: replace the input (x = 2) into the function g(x), and simplify the expression accordingly.
