Question 71811
Find the domain and range of the graph of each function.    y=log2(x-3)
(2 is the base of the log)
-------------------
y=log2(x) has domain (0,inf) and range (-inf,inf)
But you have y=log2(x-3):
The x-3 moves the x values 3 to the right and leaves the y values as they were.
So, domain is (3,inf) and range is (-inf,inf).
