f(x)  = -4 log 2 ( x + 3)  -  6

 

Note, Jenny, that this isn't as hard as it looks

 

We cannot take the  log  of 0  or a negative number...so...this implies that

 

x + 3   ≥  0      subtract  3  from both sides

 

x  ≥  -3

 

So....the domain is all real numbers  greater than  -3

 

 

 

cool cool cool
