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 [0, infty). Geometrically, the graph of this function creates a sharp, symmetrical V-shape that consists of two linear rays converging exactly at the origin (0, 0).

Geometric Properties of the Absolute Value Function
In a laboratory setting, a technician uses the parent absolute value function to record the magnitude of temperature variations. Because this function can accept any value on the number line as an input, its domain is the set of all ____ numbers.
In professional quality control, the absolute value function is used to calculate the magnitude of measurement errors. True or False: The range of this parent function is strictly restricted to non-negative real numbers, [0, infty), because the absolute value of a number represents its physical distance from zero.
Recall of Absolute Value Graph Properties in Manufacturing Quality Control
In a precision manufacturing facility, a Quality Control (QC) inspector is verifying the dimensions of a critical machine component. The target width of the component is . Any variation from this target is modeled using the parent absolute value function, where the input represents the raw deviation from the target width, and the output represents the magnitude of the error. To document this process on the quality control chart, the inspector needs to recall the key characteristics of the parent absolute value function to model the error graph. Arrange the following steps in the correct logical sequence to construct the absolute value error graph from left to right (from to ).
