Question

The function f(x) = log(little 9)x is a logarithmic function.
true or false

Answer 1

Do you mean \(\huge f(x) = \log_9(x)\)? That is read as "log base 9 of x". :) And yes, it is a logarithmic function. There is a good set of notes about it here: http://www.purplemath.com/modules/logs.htm
