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
