### Different Names for the Same Things

The input of a function is the set of numbers we are "putting in" for X. It is also called the domain. It is the number we are substituting into the function in order to get out an answer. It is also called the independent variable, because you can change what it is. It is going to be the x-coordinate of the ordered pairs when we graph them in the end. So...

X = input = domain = independent variable = x-coordinate

They all refer to the same "thing" or set of "things," more specifically.

The output of a function is the set of numbers we are "getting out" for Y. It is also called the range. It is the answer we are getting as a result of putting in an x-value. It is also called the dependent variable, because it changes as the X changes. It is going to be the y-coordinate of the ordered pairs when we graph them in the end. So...

Y = output = range = dependent variable = y-coordinate

They all refer to the same "thing" or set of "things," more specifically.

How do we find the domain and range of a relation?
