Question

How do you find the x-intercept(s) of a rational function?​

Answer 1

Step-by-step explanation:

Key Points

For any function, the x -intercepts are x -values for which the function has a value of zero: f(x)=0 f ( x ) = 0 . For rational functions, the x -intercepts exist when the numerator is equal to 0 . For f(x)=P(x)Q(x) f ( x ) = P ( x ) Q ( x ) , if P(x)=0 P ( x ) = 0 , then f(x)=0 f ( x ) = 0 .
