Which is the graph of f(x) = 3 (3/2)^x ?

The graph of the function f(x) is:

                      Graph  4

We are given a function f(x) in terms of variable x as follows:

Now, when x=0 then the graph of the function f(x) must pass through:

and when x=1 then the graph of the function f(x) must pass through:

i.e. the graph of the function should pass through the points:

(0,3) and (1,2)

Now, after looking at the graph we observe that the first and second graph do  not pass through (0,3).

Hence, graph 1 and graph 2 do not represent the function f(x).

Also, graph 3 pass through (0,3) but it does not pass through (1,2)

Hence, Graph 3 does not represent f(x)

Hence, the correct graph is: Graph 4

55 degrees because 55+55=110 degrees

the first domain and range set to the left is matched with the top relation, and the second set the set in the middle goes with the bottom relation.
