show me step by step how to find the domain of this function then graph it
g(x)=2x4

The domain of a function is the set of all possible input values which allows the function formula to work.
In this case your function are straight line.
Domain of straight line : (infinity,infinity)
OR
all values of x
For graph find any two points eg.
x = 0
g ( x ) = 2 * 0  4 = 0  4 =  4
x = 1
g ( x ) = 2 * 1  4 = 2  4 =  2
OR
In google type:
function graphs online
When you see list of results click on:
rechneronline.de/functiongraphs
When page be open in blue rectacangle type:
2 x  4
Then click option : Draw
You will see graph of your function
