A rectangular baby blanket has an area of 12 square feet. The blanket is 1 foot longer than it is wide. Which equation does NOT represent the area of the blanket? A) 1w = 12
B) w (w + 1) = 12
C) w^2 + w = 12
D) w^2 + w - 12 = 0

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.
