Which of the following are solutions to the inequality below? Select all that apply. 2 j = 6
j = 9
j = 11
j = 1

These are the multiples of 15 but what you are probably asking or what are the factors of 15

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.
