What Is the Range of a Function Example

The set of all output values of a function. Example: when the function f(x) = x2 is given the values x = {1,2,3,…} then the range is {1,4,9,…}

How do you find the range of a function?

  1. Write down y=f(x) and then solve the equation for x, giving something of the form x=g(y).
  2. Find the domain of g(y), and this will be the range of f(x). …
  3. If you can’t seem to solve for x, then try graphing the function to find the range.

Whats the range in a function?

The range of a function is the set of outputs the function achieves when it is applied to its whole set of outputs. In the function machine metaphor, the range is the set of objects that actually come out of the machine when you feed it all the inputs.
