The band has a total of 152 members. some of the members are in the marching band, and the rest are in the concert band. write an equation that models how many marching band members m there are if there are c concert band members

152-c=m
(m is the number of marching band members)

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.
