Question

Find the domain. Y=2x/2

Answer 1

The domain is group/set of numbers that will work for the equation

if no domain is specifiedl, then the domain is usually the set of all real numbers

to find the domain, find which numbers will violate any rules, such as dividing by zero
if there are any, then just say that the domain is all real numbers except these numbers exg

if you had an equaiton y=2/x then x cannot be zero because 2/0 is undifined and impossible so the domain would be all real numbesr except 0

domain is all real numbers
