The graph shown represents the equation y=3(1/3)^x

Statements #1-4 are all true. Statement 5 is false due to the fact that when x = 0, y = 3. 

The correct answer is: b

Period is the time it takes for one “cycle” to complete. in the parent sine function, period is 2*pi since sin(0) = 0, sin(pi/2) = 1, sin(pi) = 0, sin(3pi/2) = -1, and sin(2pi) = 0. at that point, the sequence repeats itself. i’m not sure if your graph is similar to the sine function since you didn’t provide a picture, but you can find the period by looking at a graph.
