1. The problem statement, all variables and given/known data This is the solution, the question was find its domain. 2. Relevant equations How does |X| (less than or equal to) 4, when a negative number is inputed into -2x how does that = a positive number? 3. 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?
