graph the funtion f(x)= log(base 3) (x-1) +2

Answer:

Hi judyg21,
First convert log(base 3) (x-1) to (1/log3)(log(x-1)),
this is log (base 10) you could use ln (natural log) if you want also; but stick
to log for this problem and investigate other bases.
then add 2
Use your graphing calculator and input:
y= (1/log3)(log(x-1))+2
