Master Determining the domain of a function using interval notation

In this video I show you how to find the domain of a function using interval notation. We will discuss how to identify the domain of polynomials, rational functions, and radical functions.

Thanks for the review! I swear, if it weren't for your explanations, I wouldn't remember much of anything from high school or college! You have helped me teach and tutor my daughter with ALL her math homework! Doing Pre-Calc right now, and I have been relying on your vids for years! Fantabulous stuff! I recommend you all the time!!!

amazing job but i have to ask about the last example, it seems wrong because if we applied any number less than -3 for example -4 or -5 it will also give us a negative number, wouldn't the correct answer be (-3, infinity) ?
