Round 328 to the nearest hundred

It would be 300 because its less then 330 its goes down to the nearest 100. and it above 330 or it is 330 it goes up to the nearest 100. so your answer would be 300. 

328 rounded to the nearest hundred would be 300.

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.
