Domain: all Real x;
Range: all Real l

Explanation:

Your function is a Linear Function that can be represented graphically by an infinite straight line.

The function can accept any value of x and gives, as output, any value of l.
The domain will then be all the Real x while the range will be all the Real l.

Graphically your function gives a line like this one:
graph{5x-4 [-10, 10, -5, 5]}
