Which function is graphed below?

y = 3* (1/3)^x

Step-by-step explanation:

Step 1 :

One way to find the function of a given graph is to substitute different values of x , determine the y value and see if matches the graph.

Step 2 :

Consider the function, y = 3* (1/3)^x.

When x = 0, y = 3

         x = 1 , y = 1

         x = 2 , y = 1/3

        x = 3 , y = 1/9

We see from the graph that these points are plotted in the graph

Hence the function plotted in the graph is y = 3* (1/3)^x
