If denise wanted to create a function that modeled a base of 12 and what exponents were needed to reach specific values, how would she set up her function?

I had these options :

f(x) = x12
 f(x) = log12x
 f(x) = 12x
 f(x) = logx12
my answer is  f(x)=log 2x.

Thats where they was ported and the fields that noone really knew much about needed tended, so they put slaves out there do free work and huge profits and so on the north decided to hold its own and was more different way of survival did not have same climate conditions to afford protecting slaves from winter so expenses be diff from south
