Question 387497: Hello,
Please help me solve this problem.
What is the domain of P? P(x)=xsquare-2x+1
Answer by rapaljer(4671)   (Show Source):
You can put this solution on YOUR website! Domain is ALL REAL VALUES of x. Interval notation (-inf,inf).
For more help with Domain and Range, please see my own website! Click on my tutor name "rapaljer" anywhere in algebra.com, then look for the link on my Homepage that says "Rapalje Videos in Living Color." Select either Intermediate or College Algebra, depending upon your level of math, and you will be able to see FREE videos from my own classes a few years before I retired. My explanation is what you might call an "alternate" or "non-traditional" explanation. It might be helpful to see another explanation that might be different from the one you were given in class. You may have to download RealPlayer if you don't already have it, but this too is a FREE download. Everything is FREE!! I hope it helps you.
