Graph points A(-1, -1), B(-1, 3) and C(3, 2) on the coordinate plane. What is the area of triangle ABC? A) 7 square units B) 8 square units C) 14 square units D) 16 square units

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.
