The diameter is a line that stretches across the middle of a circle from end to end. The radius is one half of this line, stretching from the center of the circle to a point on the side of the circle. This means that the diameter is 2 times the length of the radius. 2 times 2 is 4, meaning that the diameter is 4 inches.
a₅ = 10
a₁₀ = 20
a₁₅ = x
-------------------------------------------------------------------------------------------------------------------
Note that from a₅ to a₁₀, there is a addition of 10. This means that for every x(₅) jump, you add 10 to the whole number.
-------------------------------------------------------------------------------------------------------------------
So in this case:
a₁₀ = 20
a₁₅ = x
a₁₀ (+₅) = 20 (+10)
a₁₅ = 20 + 10
a₁₅ = 30
Note that: a₁₅ = x = 30
-------------------------------------------------------------------------------------------------------------------
x = 30, or (A) is your answer

In general, the domain is the set of all x-values for the graph.
The issue here is that this isn't the graph of a function. A function has at most one y-value for each x-value and this graph has an infinite number of y-values for the single x-value of 1.
So, either your teacher is wanting you to say the domain is {1}, because that's the only x-value used by the graph, or they're wanting you to say this is a trick question, because this isn't the graph of a function.
The range is the set of all y-values, which is -9<y<9, but again, do they intend this to be a trick question?
