In mathematics the domain or set of departure of a function is the set into which all of the input of the function is constrained to fall. First we learn what is the Domain before learning How to Find the Domain of a Function Algebraically What is the Domain of a Function. Attention one thing is y 1 2X 5 where the domain will be all real for everything that I explain and another thing is if the function is given by Y 1 2X 5 in this case the denominator 2X 5 can not be zero because there is no divison between zero then what is done is to see where that denominator is equal to zero this is achieved thus 2X 5 0 and now we clear the value of X.
