Key Concepts

Graph Transformations

Graph transformations refer to operations applied to the basic graph of a function that result in shifts, stretches, compressions, or reflections. In this context, the absolute value function is modified by a horizontal scaling factor, which changes the steepness of the graph, and by a vertical translation that shifts the entire graph upward. Recognizing these changes is crucial for sketching the graph accurately.

Absolute Value Function

This concept involves the function that returns the non-negative value of its input, defined as |x|. It is fundamental in understanding how the output behaves with respect to the input, especially since the expression inside the absolute value can change signs yet the result remains non-negative. This characteristic leads to a distinctive V-shaped graph when plotted.

Domain and Range of Functions

The domain of a function is the set of input values for which the function is defined, while the range is the set of possible output values. For functions involving absolute values, especially with additional transformations, understanding these concepts helps in determining where the function exists and what outputs it can take. In the example provided, knowing that the absolute value cannot produce negative results is key to identifying the range after the vertical shift.
