Miller · Answer 1

() = 0 which means | = 1

Step-by-step explanation:

The only way for () = () is when | = 1

You notice from these two equations that

() = - 2| + 1| + 1 and () = - 4| + 2| + 2 = 2 * (-2| + 1| + 1) = 2 * ()

This is a very restricted equation.

To solve () = 2 * (), the only solution is when () = 0 which means | = 1
