Key Concepts

Domain of a Function

The domain of a function consists of all input values for which the function is defined. For radical functions with an even index, such as a square root, the radicand must be non-negative, which restricts the domain to values that satisfy this condition.

Function Transformations

Function transformations, such as horizontal shifts, allow one to adjust the input to the function. For example, replacing x with (x - a) in the radicand shifts the domain by a, making it possible to specify the starting point of the domain as required.

Radical Functions

Radical functions involve taking a root of a variable expression, typically the square root when no index is written. These functions are defined only for values that make the radicand non-negative, which directly influences their domain.
