Boundary value analysis in mathematics involves testing the behavior of a function at the boundaries of its domain. By evaluating the function at the boundary values, we can determine if there are any special cases or exceptions that need to be considered. This technique helps ensure that the function behaves as expected at critical points and can reveal any potential errors or inconsistencies in the function's behavior. Overall, boundary value analysis is a systematic approach to testing mathematical functions to ensure their accuracy and reliability. **

Piecewise defined functions with absolute value symbols are functions that have different rules or expressions depending on the input value. The absolute value symbols indicate that the function will have different behaviors for positive and negative values of the input. For example, a piecewise defined function with absolute value symbols might have one expression for x ≥ 0 and a different expression for x < 0, with the absolute value symbols ensuring that the function is continuous at the point where x = 0. **
