Thank you so much. I truly appreciate the time you took to put this together.
You're welcome! I am so glad that these videos are helping you in your Math class. Keep working hard - you got this! 😀
thank you
You're welcome! Keep up the great work and thank you for being a part of this community - you rock! 😀
The only question I have is how do I go about writing the domain in interval notation? I'm struggling to express all real numbers except -5, and +5 in interval notation. I thought it would be notated as (-infinity, -5) U (5, infinity) but it is marking that as incorrect. I believe it is incorrect because I am not account for all of the integers between, but not including, -5 to +5.
Hi there! You're almost there - keep in mind that this is also a function in between -5 and 5 as well (just not including those numbers!). The interval notation of the domain should be: (-∞, -5)u(-5,5)u(5, ∞). Hopefully this helps! 😀
