The table shows the circumference of a tree in centimeters, y, for x years.
Which descriptions are true of the function shown in
the table? Check all that apply.

Ithink is a. true, but not sure

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.
