To get to school each morning, Vanessa takes a horse 19.33 19.3319, point, 33 kilometers and a train 2.27 2.272, point, 27 kilometers. In total, the journey takes 26.48 26.4826, point, 48 minutes.

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.
