Question

find the domain and range of rational function​

Answer 1

Answer:

To find these x values to be excluded from the domain of a rational function, equate the denominator to zero and solve for x . For example, the domain of the parent function f(x)=1x is the set of all real numbers except x=0 . Or the domain of the function f(x)=1x−4 is the set of all real numbers except x=4 .
