Domain and Range of Rational Functions – Varsity Tutors

How do you find the range of a function algebraically y=(x+5)/(x-2 …

To best way to find the range of a function is to find the domain of the inverse function. To find the inverse function of a function you have to substitue x with y , and vice versa, and then find y .

Domain and Range of Rational Functions – Varsity Tutors

So, the range of the function is the set of real numbers except 0 . Example 1: Find the domain and range of the function y = 1 x + 3 – 5 . To find the excluded value in the domain of the function, equate the denominator to zero and solve for x .

Finding Domain and Range

Functions are a correspondence between two sets, called the domain and the range. When defining a function, you usually state what kind of numbers the domain (x) and range (f(x)) values can be. But even if you say they are real numbers, that doesn’t mean that all real numbers can be used for x. It also doesn’t mean that …

You can solve this inequality to see that the domain then is (-8,-6]?[0,8). This just excludes the open interval (-6,0) on which t(t+6)<0. So what is the image of g ? (Note: the range can be taken to be (-8,8), but I think you want only the more restricted set of values actually assumed by g; the terminology ...
