Since there are NO denominators, and NO radicals, there are NO excluded values. The domain is all real values or (-inf, inf).

If f%28x%29+=+%283+-+5x%29%2F5 was the way the function was made, you would not have any excluded values for the domain and the range due to no limitations because it is a linear line.

To find excluded values in functions

1. Set anything inside a square root sign >=0.
2. Set the denominator (before simplifying...i.e. before any cancelling) to zero.


The solutions to either of those steps - values that make an expression in the denominator =0 or in a square root sign <0, are excluded.


In this case set 5=0. That never happens. Nothing is excluded.
