Determine if domain and range are a function
WebSep 5, 2024 · The range is also determined by the function and the domain. Consider these graphs, and think about what values of y are possible, and what values (if any) are not. In each case, the functions are real-valued: that is, x and f(x) can only be real numbers. Quadratic function, f(x) = x2 − 2x − 3. WebFunctions assign outputs to inputs. The domain of a function is the set of all possible inputs for the function. For example, the domain of f (x)=x² is all real numbers, and the …
