x intercept   =   where y = 0  .....so

0  = log2(x - 3) + 1

-1  =  log2(x - 3)

In exponential form

2^(-1)  = x - 3

(1/2)  = x - 3

(1/2) + 3  = x intercept  =  3.5

 

y intercept.....none

 

Increases from right to left on the domain

 

Domain  (3, infinity)

Range.....all reals

 

Asymptotes   x  = 3

 

End behavior    :  down on the left....up on the right

 

 

cool cool cool
