WebJul 22, 2024 · Finding the Domain of a Function Defined by an Equation In Functions and Function Notation, we were introduced to the concepts of domain and range. In this section, we will practice determining domains and ranges for specific functions. WebFor every polynomial function (such as quadratic functions for example), the domain is all real numbers. If f (x) = a (x-h)² + k , then if the parabola is opening upwards, i.e. a > 0 , …

WebAlgorithm : i) Put y = f (x) ii) Solve the equation y = f (x) for x in terms of y. Let x = ϕ ( y). iii) find the values of y for which the values of x, obtained from x = ϕ ( y) , are real and in the … WebDomain and Range Worksheet with Answers. The domain of a function is the complete set of possible values of the independent variable. In plain English, this definition means: The domain is the set of all possible x -values which will make the function "work", and will output real y -values.
