Definition of the Domain of a Function For a function f defined by an expression with variable x, the implied domain of f is the set of all real numbers that variable x can take such that the expression defining the function is real. The domain can also be given explicitly. also a Step by Step Calculator to Find Domain of a Function is included. WebThe behavior of rational functions (ratios of polynomial functions) for large absolute values of x (Sal wrote as x goes to positive or negative infinity) is determined by the highest degree terms of the polynomials in the numerator and the denominator. This particular function has polynomials of degree 2 in both the numerator and the denominator.
