Hello, findmehere.genius!
I graphed the first one . . . Got the same answer as runninggag.
. Find value of I'll graph it in baby steps . . .
We know what looks like: Code:

 *
 *
 *
     *     
* 
* 
* 

Then we have: .
The absolute value says: anything below the xaxis is reflected upward. Code:

*  *
*  *
*  *
*  *
     *     


Then moves the graph 2 units to the right. Code:
*  *
*  *
* *
 * *
   +  *     
 2

Then moves the graph down 2 units. Code:

*  *
*  *
*  *
   *    *   
 * *
 *

Finally,
. . Anything below the axis is reflected upward. Code:

*  *
*  * *
*  * * *
   *  +  *    
 2

There!
What does this graph have in common with ?
. . (See the first graph.)
We find that the graphs coincide for: .
