In Problems 47鈥� 62, find the domain of each function.

f(x)=x2x2+1

Short Answer

Expert verified

The domain of the given function is the set of all real numbers.

Step by step solution

01

Step 1. Given Information

In the given problems we have to find the domain of given function.

f(x)=x2x2+1

02

Step 2. The function tells us to divide x2 by x2+1. 

Since these operations can be performed on any real number, we conclude that the domain of fis the set of all real numbers.
