Which value could be part of the domain of a sequence as a function?

a) 1/6

b) 6

c) .6

d) -6

B. Because a domain is the "x" value  and on a graph you would notice the the "x" are all positive numbers (to the left). Hope that made sense. A range is the "y" value and are negative numbers (to the right) on a graph just in case you would like to know that as well:)

Maybe the answer is 20mm. all i really did was just multiply, which is obvious.
