This is something that is useful later, mostly when looking at graphs of radical functions. For example, the graph of y=sqrt(x-3) will only be defined for values of x that are greater than or equal to 3.
@@AllAroundMathGuy Ohh I see. By the way, thank you so much for all of this. I can see that inside of you, you are really a generous person because you are always imparting knowledge to the world. Once again, THANK YOU!

Hi, when do you reverse an inequality sign? Thank you! Btw, this video is very helpful for my pre-calc! :)
When dividing with a negative value.
thx dude really helps
You're welcome - glad it helped! 🙂
Hello! Curious to know what the point of these equations were! :)

How about restrictions of √x^2
No restrictions on square root of x-squared... squaring the x-value first gives a positive number or zero, which is fine under the square root

How about cube roots?
they would be all real numbers.
They would be XER but I think the deniminator can not be zero so xer but x not =0
Cube roots don’t need restrictions, only when the index is even like a square root or a fourth root
Thanks for the video!
athens 2004 was a great success
