Answer:
Required logarithmic function is :

Step-by-step explanation:
We have been fiven that table for the logarithmic function is:
x	f(x)
9	2
27	3
81	4
which can be rewritten as:
x	f(x)
3^2	2
3^3	3
3^4	4
Which are basically powers of 3
So we can use logarithmic function as 

Hence required logarithmic function is :

 
        
             
        
        
        
It would be (a) because it is  now

Answer:
c
Step-by-step explanation:
 
        
                    
             
        
        
        
The answer is y=(1/2)x -5
You are given the slope and a core donate pair so you plug them in to the equation. 2=x. -4=y. And (1/2)= m
Then work out like a one step equation
