# Absolute Value

The absolute value of a real number is its numerical value without regard to its sign. So, for example, 3 is the absolute value of both 3 and −3.

The absolute value is closely related to the notions of magnitude, distance, and norm in various mathematical and physical contexts.

Absolute value of a number is the distance from the number on the number line to zero

Example:

|-7| = 7

| 7 | = 7

# Domain of a Function

The domain of a given function is the set of "input" values for which the function is defined. For instance, the domain of cosine would be all real numbers, while the domain of the square root would only be numbers greater than or equal to 0 (ignoring complex numbers in both cases). In a representation of a function in a xy Cartesian coordinate system, the domain is represented on the x axis.
