Since $f(x)$ will always be non-negative, the number $-3$ is in the codomain of $f$, but it is not in the range, as there is no input of $x$ for which $f(x)=-3$.

It is possible there are objects in the codomain for which there are no inputs for which the function will output that object.įor example, we could define a function $f: \R \to \R$ as $f(x)=x^2$. All we know is that the range must be a subset of the codomain, so the range must be a subset (possibly the whole set) of the real numbers. But, without knowing what the function $f$ is, we cannot determine what its outputs are so we cannot what its range is. From this notation, we know that the set of all inputs (the domain) of $f$ isi the set of all real numbers and the set of all possible inputs (the codomain) is also the set of all real numbers. See examples of range with numbers, functions, and practice questions. In the function machine metaphor, the range is the set of objects that actually come out of the machine when you feed it all the inputs.įor example, when we use the function notation $f: \R \to \R$, we mean that $f$ is a function from the real numbers to the real numbers. Solution: (a) The range for group of girls 10 6 4. Learn what range in math is, how to calculate it using formulas and steps, and how to interpret it for data sets, functions, and graphs. The range of a function is the set of outputs the function achieves when it is applied to its whole set of outputs.
