y = f(|x|) = f|x| (not a fan of this notation outside of logarithms, but that's me)

Hopefully this has cleared up all the confuzzlation.

-
f(|x|) graphs as A V-shaped curve in QI and QII with the vertex at the origin and slopes of - 1 and + 1.

Its a 'v'
If x<0 we have y=-x and if x>0, its y=x.
Tip of v is at the origin.
