can you redo the question because i can't tell if the last the colums are answeres or the rest of the equation ..
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 :

Because it is 5 units to the left of 3 on a horizontal number line
