y=2|x|-1
What operation do I do with x?

x is in absolute value bars. Just saying it will be positive no matter what even if it was negative. Treat it as 2(x) -1
wait are you just wondering what it is or how to graph/solve it?
Ohh I get it now, thanks a lot!
For whatever number x is, it will remain positive when evaluated. The point of the absolute value function is to determine the distance a number is from zero. Distance is NEVER negative, only positive. Hope that helps.
