This week we learned about domain and range. In the beginning I didn’t really know what to do with inputs and outputs but when we got deeper into the lesson and did more examples I started to get it a little more. Abide by the BEDMAS rule when solving a function, you also replace the variable with the number given for the (x) value.
Domain: the independent(input) variable in the relation.
Range: the set of all numbers for the dependent(output) variable in the relation.
Function: a special realtion where every input(x) has only one output(y).
