PreCalculus 3: Graphing Polynomial & Rational Fcts (26 of 29) Polyn, Domain & Range=?, Syn Division

In this video I will demonstrate the 3-steps used to graph (with horizontal and vertical asymptotes) and find the domain and range of y=(2x^2-4x+5)/(x^2-2x+1).

You are great. Thanks a lot for everything.

when you use 1/x^2 as a tool to change form of function does x=0 get excluded from domain since your tool violates the div by zero rule or does the rule only apply to initial rational function y=f(x)/g(x)? Thank you!!!
