Find the Domain of Each Function Using Interval Notation: f(x) = 5/sqrt(x - 3) PLUS 2 MORE EXAMPLES!

For the following exercises, find the domain of each function using interval notation.
f(x) = 5/sqrt(x - 3)
f(x) = (2x + 1)/sqrt(5 - x)
f(x) = sqrt(x - 4)/sqrt(x - 6)

Your videos are so helpful. I need to figure out how to do certain problems in my math book and you seem to always have the exact problem. super nice for learning and retaining.

I watched a prior video on these type of problems from The Organic Chemistry Tutor, but your style of doing it was way quicker and less stressful. Although, I did combine a combination of both of your skills to solve these type of problems. Instead of saying x≠6 I just said x>6, and that way I can be reminded of the direction I have to shade in. Oh, and it also makes one less restriction, so now you'd just have 2.
