Answer:
Option (3) is correct.
The Function of given graph is
Step-by-step explanation:
Given : A graph .
We have to determine the function is shown on the graph.
Since, The given graph is a logarithmic graph.
So, Equation of logarithmic function is
And Given coordinate on graph are (1,0) and (3,1).
Then Put x = 3 and y = 1, we have,
We know ,
Therefore, a = 3
Thus,
Also, Put x = 1 , we get
Thus, The Function of given graph is
