Absolute Value Function
The absolute value function is fundamentally defined by the equation . Because the absolute value can be cleanly computed for any real input, its domain is all real numbers, expressed as . However, since absolute value represents a number's physical distance from zero, the output can never be negative. Therefore, the range is strictly restricted to non-negative real numbers, or . Geometrically, the graph of this function creates a sharp, symmetrical V-shape that consists of two linear rays converging exactly at the origin .
