What are absolute value functions used for?

Absolute value functions are an important concept in mathematics that have many practical applications. These functions are used to determine the distance between a number and the origin (zero) on the number line. The absolute value of a number is defined as its distance from zero, regardless of its sign. In other words, it gives the magnitude of a number, ignoring its direction.

What are absolute value functions used for?

The primary use of absolute value functions is to obtain the magnitude of a number, irrespective of its positive or negative sign. By considering the distance of a number from zero, absolute value functions help us understand the numerical value without considering direction.
