Find roster form of the given Set

    Let B be the non empty sets,
    B ={(x,y):y = e^x, x belongs to set of real numbers}
    Write the set in roster form.

    By "roster form" you mean a listing of all members, right? You understand there are not only an infinite number but an uncountable number of members in this set, don't you. So you cannot "list" them even in principle (as, for example, {(1, 1), (2, 4), (3, 9), ...}). That's pretty much what "uncountable" means.

    @Hallsoflvy Yes roster method means to list all the element in curly brackets.
