Youre in y10? Is this higher or further maths or ...? But something like

are decent. Not sure what you mean be ER.
If you want to "revise" gcse maths, so a quick review guide, something like the full gcse handbook towards the bottom of the page on
https://m4ths.com/gcse.html
is decent to flick through. Though practice and working through any mistakes/uncertainty are the key things.

yeah im y10- this is further maths and thanks for the links
when i say the ER stuff i mean when you have to write the domain and range in terms of x so for example for a function of f(x) = 2x the domain would be x (its like a euro sign but with only one dash which is why i put the E bc its most like it) (and then an R but its got a line through the middle of the R) i mean this ↖️
sorry im not really good at explaining it but thanks for the links!

R is the set of all real numbers (number line). "e" means "is a member of". So
x e R
simply means the variable x can take any (real) value. So the domain has no restrictions.
