Which of these is a function? {(0, 1),(1, 2),(1, 5),(2, 9)}
{(0,4),(0,5),(0, 9),(0,23)}
{(0.4),(2, 4),(3, 7),(4.9)}
{(6.0),(6, 1),(6, 7),(6,11)}

The answer of this question is 672 .

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.
