Question

The function f has a domain of 1,3,5,7 and a range of 2,4,6. Could f be represented by 1,2. 3,4. 5,6. And 7,2. Justify your answer

Answer 1

Yes, a function with those domain and range values could certainly be represented by those points. (1,2) and (7,2) are points with separate domain values but identical range values. This is allowed because every x value is only assigned one y value.
