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
