Domain And Range Functions Gcse The domain of a function includes all of the allowable input values The range of a function includes all of the possible output values
Functions Domain amp Range Remember The domain of a function is the set of values x can take The range of a function is the set of values f x can take If you have a quadratic function the vertex is a particularly useful thing to work out A sketch of your function y f x is also vital Introduction to function notation aims to familiarise students with f x and looks at substitution of values Also included finding the range of a function given its domain which appears on the IGCSE Complete differentiated lesson with examples and questions to display on the whiteboard
