What does it mean “Range”?

$c = 2 , x = Range[1,3,1] , y = c*x^2$

I don't know how to solve. can anybody help me to solve? Thanks.

EDIT

this's the result : http://bit.ly/11PHGqG how this happen?

Well, $$c = 2 , x = Range[1,3,1] , y = c*x^2$$ is not a question, so I don't know what you mean by "What is the answer?" Can you provide any context that would help other people figure out what you mean? –  Zev Chonoles Jun 20 '13 at 21:08
bit.ly/11PHGqG it returns $x = {1,2,3}$ can anybody explain how this happen? –  Elmi Ahmadov Jun 20 '13 at 21:15
Please give the context. –  Tony Piccolo Jun 20 '13 at 23:03

The $x$, $y$, and $z$ in Range[x, y, z] are called the min, max, and step respectively. It specifies the sequence of numbers $$x, x + z, x + 2z, \ldots$$ which starts at $x$, increases by $z$ each time, and stops after reaching $y$.
