Question

y=2|x|-1

What operation do I do with x?

Answer 1

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

Answer 2

wait are you just wondering what it is or how to graph/solve it?

Answer 3

Ohh I get it now, thanks a lot!

Answer 4

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.
