WebTo find the domain of a rational function y = f (x): Set the denominator ≠ 0 and solve it for x. Set of all real numbers other than the values of x mentioned in the last step is the domain. Example: Find the domain of f … WebJul 18, 2024 · Example 4.7.1. Find the domain and range of the following function: f(x) = 5x + 3. Solution. Any real number, negative, positive or zero can be replaced with x in the given function. Therefore, the domain of the function f(x) = 5x + 3 is all real numbers, or as written in interval notation, is: D: ( − ∞, ∞). Because the function f(x) = 5x ...

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. WebJul 13, 2024 · Find the Domain of a Rational Function Division by zero is undefined. Having a zero as the denominator is equivalent to division by zero thus is also undefined. The rational function is undefined for any value of the variable that gives a zero denominator. Find these values by creating an equation to solve. flavcity curry chicken
