Can I write it just like

f(x)={ x+|x| if x>1

f(x)={ x+|x| if x>1

Where x > 0, you get f(x) = 2x.

Where x < 0, you get f(x) = 0.

Does that help?

Where x < 0, you get f(x) = 0.

Does that help?

Minor point: don't forget x = 0 in your definition.TD said:Where x > 0, you get f(x) = 2x.

Where x < 0, you get f(x) = 0.

Does that help?
