In humans, each cell nucleus contains 23 pairs of chromosomes a total of 46 chromosomes. The first 22 pairs are called autosomes which look exactly the same in both males and females. The 23rd pair of chromosomes is called an allosome. These sex chromosomes differ between males and females. Females have two copies of the X chromosome, while males have one X chromosome and one Y chromosome.
Range refers to the y-axis. Domain refers to the x-axis. Range refers to the y-axis. Domain refers to the x-axis.
All of the values that can go into a relation or function (input) are called the domain. All of the values that come out of a relation or function (output) are called the range. Range may also be referred to as image. Note that both relations and functions have domains and ranges. The domain is the set of all first elements of ordered pairs (x-coordinates). The range is the set of all second elements of ordered pairs (y-coordinates). Only the elements used by the relation or function constitute the range. Domain: all x-values that are to be used (independent values). Range: all y-values that are used (dependent values).
