Domain of a function refers to the set of possible input value, all the input values shown on the x-axis (x--values), then we can say that:
a. Domain of the functions is all real numbers excluding zero, because a number divided by 0 it's undefined.
b. To make a table of values, we can use the x-values you want and substitute it in the function, I'm going to use x=1 to x=5
The graph would be:
Five ordered pairs generated:
(1, 5000)
(2, 2500)
(3, 1666.6)
(4, 1250)
(5, 1000)
