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 :
ANSWER
B) -1
EXPLANATION
From the graph,
f(1)=3 and f(4)=0.
The average rate of change from x=1 to x=4 of this function is,
Substitute the functional values
Simplify
The correct choice is .
