F (x) = 2lxl? (graphing absolute values) I'm a little confused.

I see. Imagine you have f (x) = |x|. It's a V shaped graph.

Now if f (x) = |x|, 2f (x) = 2|x|.

Graph Transformation Rule:

af (x), multiply y-coordinates by a.

*Ultimately, you'd still have a V shaped graph in 2f (x) = 2|x|, but the y values of all the coordinates in f (x) = |x| would have to be multiplied by 2 giving you 2f (x) = 2|x|.
