# Finding range algebraically

Overall, the steps for algebraically finding the range of a function are: Write down y=f (x) and then solve the equation for x, giving something of the form x=g (y). Find the domain of g (y), and this will be the range of f (x). Note: if there are

## Domain and range of a function given a formula

The range here is going to be, we could say f (x) is a member of the real numbers such that f (x) does not equal zero. f (x) does not equal zero. So the domain is all real numbers except for zero, the range is all real numbers except for zero. So the big takeaway here is the ## 4 Ways to Find the Range of a Function

Arrange the known values in the set in numerical order: {–5, –2, 1, 3, 5, 7, 7, 10}. The range is the difference between the largest value and smallest value. x must be either the largest or the smallest value in the set. range = x – smallest
