Question

Let () = −2| + 1| + 1 and () = −4| + 2| + 2. When does () = ()?

Answer 1

Answer:

() = 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
