Using the same example as above, the domain of f(x) = x 2 in set notation is: {x | x∈ℝ} The above can be read as "the set of all x such that x is an element of the set of all real numbers." In other words, the domain is all real numbers.

Purplemath. You never know when set notation is going to pop up. Usually, you'll see it when you learn about solving inequalities, because for some reason saying "x < 3" isn't good enough, so instead they'll want you to phrase the answer as "the solution set is { x | x is a real number and x < 3 }".How this adds anything to the student's understanding, I don't …1 12.38 −0.8625 3 4 π ( pi) 198 In fact: Nearly any number you can think of is a Real Number Real Numbers include: Whole Numbers (like 0, 1, 2, 3, 4, etc) Rational Numbers (like 3/4, 0.125, 0.333..., 1.1, etc ) Irrational Numbers (like π, √2, etc ) Real Numbers can also be positive, negative or zero.
