Answer:

Last graph on the right.

Explanation:

Try substituting some values for x and see which graph is valid.

when x = 0, y = f(0) = 3
(2/3)^(0) = 3 (1) = 3

When we compare this to the graphs, we immediately see that the first 2 are not correct because in those cases, when x=0, y = 6 (i.e not 3).

Next we try x = 1

when x = 1, y = f(1) = 3
(2/3)^(1) = 3 (
(2)/(3)) = 2

Comparing the graphs ones again, show that only the last graph has x=1 and y = 2.
