ℝ All symbols Usage The set of real numbers symbol is the Latin capital letter “R” presented with a double-struck typeface. The symbol is used in math to represent the set of real numbers. Typically, the symbol is used in an expression like this: x ∈ R Because that value causes the denominator to be equal to zero, then the domain of that function will be the set of all real numbers except the value x = 1. In this case, we have: f(x) = x^2 - 4. There is no value of x that causes a problem for this function, then the domain is the sett of all real numbers. Correct option D.Real numbers. Real numbers are the set of numbers that consists of both rational and irrational numbers. They can either count to be positive or negative.
