 Domain and Range of a Function,
a selection of answers from the Dr. Math archives.
 Domain and Range
 Can you please explain about domain and range?
 Domain and Range of Functions
 I am learning in school about the domain and range of functions.
Why are they called domain and range? And where did they come from?
 Finding the Domain of a Function
 How do you find the domain of this function: f(x) = (4+x)/(x^29)?
 Finding The Domain and Range
of a Function
 How do I find the domain and range of a function? My problem is
f(x) = x squared 2.
 How to Find the Range of a Function
 How do you find the range of a function like g(x) = (x+1)/(x^21)?
 Domain, Range, and Asymptote
 How do you find the domain, range, and asymptote of a function?
 Range
 If f(x) = x3/x+3, I know the domain to be all Reals except for 3.
The range, however, is all Reals except for 1. I don't know how they get
the 1 algebraically.
 Range and Domain of a Graph
 Determine the domain and range of the graph of "f" that starts at
( 2,3), goes down to (0,0), and ends at (3,4).
 Range of a Function
 Describe the range of the function g(x) = e^(2x).
 Natural Domain of a Function
 Some inputs don't make sense for some functions.
 Functions: Domain, Range, and Piecewise
 What are piecewise functions? What are open and closed points? How do you
figure out the domain and range of a function without graphing it on a
calculator?
 Domain and Range of x^x
 What is the domain and range of x^x?
 Domain and Range of an Inverse Function
 Why is the domain of a function equal to the range of the inverse function?
 Domain, Asymptotes, Intercepts
of a Function
 What is the domain of this function? What asymptotes does it have?
What are the x and y intercepts? Etc...
 Domain of a Composite Function
 I don't completely understand how to find the domain of a composite
function. Could you please explain it?
