## Homework Statement

This is the solution, the question was find its domain.

## Homework Equations

How does |X| (less than or equal to) 4, when a negative number is inputed into -2x how does that = a positive number?

## The Attempt at a Solution

On the graph to me All X values < 0 should be negative or atleast until -5

Because the -2x if |x| < 4

If we put f(2) -2 * |2| = -4 which works on the graph but if I put -2 which would equal positive 2 because of the absolute value the graph seems to not make sense for me.

f(-2) should equal -4 as well right?
