# What is the domain and range of l(x) = 5x-4?

Oct 31, 2015

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]}
