La expresión = ( − 1) 2 relaciona la altura con el desplazamiento horizontal , representado en la gráfica. El desplazamiento para el cual no hay altura es:
A. = 2
B. = 1
C. = 0
D. = −1

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.
