I don't understand domain or range AT ALL!
I don't get the topic at all, everytime I try understand it from the markscheme, its like a different way of working it out each time, I watch youtube videos to understand it, it doesn't make sense to me at all. How do you use the notations. When do you have to use for example: 4<x<7 and when do you use x<7 and x>4 when do you use these notations? I've done a ton of function questions but I always get stuck in trying to find the range and domain
