Key Concepts

Range of a Function

The range of a function is the set of all possible outputs (y-values) that result from substituting the domain values into the function. For functions involving absolute values, the inherent nonnegativity of the absolute value expression plays a key role in defining the range, which can be altered by subsequent vertical translations or other modifications.

Function Transformations

Function transformations include operations such as translations, reflections, stretches, and compressions that modify the graph of a function without changing its basic structure. Horizontal shifts affect the input values, while vertical shifts alter the output values. Understanding these transformations helps in determining how operations like translations affect the domain and range of a function.

Absolute Value Function

An absolute value function takes the form f(x) = |x| and outputs the nonnegative distance of x from zero. This function is defined for all real numbers, and its basic output is always zero or positive. Understanding the absolute value is essential for analyzing how the function behaves, particularly when the expression inside the absolute value is modified by other operations.

Domain of a Function

The domain of a function consists of all possible input values (typically x-values) for which the function is defined. In many functions, particularly those involving absolute values or polynomials, the domain is all real numbers. Determining the domain involves analyzing the function to see if any restrictions, such as division by zero or even-numbered roots of negative numbers, might occur.
