+2

 

 

Note that   g(x)  =  - 2  / (-x - 3) +5    can be written as   g(x)  =  - 2  / - (x + 3) + 5 =  

2 / (x + 3)  + 5

 

The   (x + 3)  part  shifts the graph of   1/x   to the left by 3 units

 

The "2"   vertically stetches the parent graph by a factor of 2

 

Additionally, the "+5"  shifts the parent graph up 5 units 

 

So  putting all these together......the parent function is shited to the left by 3 untis, up by 5 units and vertically stretched by 2 units

 

See  the graphs of   1/x  , 2/x , 2/ (x + 3) and  2 /( x + 3) + 5  here :
