Answer:

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]}
