Question 607736
You would type in log(x+1)/log(3) when plotting this function. Doing so will give you


{{{ drawing(500, 500, -10, 10, -10, 10,
 graph( 500, 500, -10, 10, -10, 10,0,log(3,(x+1)))

)}}}


Note: the bottom portion will continue onto negative infinity.


From the graph, we see that the domain is {{{x>-1}}} and the range is the set of all real numbers.
