Finding which number supports the idea that the rational numbers are dense in the real numbers? a fraction between x/2 and x/3
an integer between –11 and –10
a whole number between 1 and 2
a terminating decimal between –3.14 and –3.15

Idon’t feel like doing the math but you need to do 2.24 divided by 7

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.
