The rectangular pupil of an octopus is estimated to be 20 millimeters long with an area of (20x-200) square millimeters. write an expression that represents the perimeter (in millimeters) of the octopus pupil.

Need the graph to answer this.

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.
