Let f(x)= (P/Q)/(R/Q) and g(x)= (P/R), where P, Q, and R are polynomials. Explain how to find the excluded values of F and why you should not try to find those values by examining G.

  f(x) is undefined where Q=0 or R=0.

Step-by-step explanation:

The function f(x) will be undefined if any of the denominators is zero. That will be the case for Q=0 and for R=0. (You can find some of the excluded values by examining g(x) = P/R.)

To find the excluded values, find the zeros of the denominator polynomials.

___

By itself, examining g(x) may not tell you all of the excluded values of the domain of f(x). The zeros of Q also need to be excluded.
