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?
