Which of the following best describes the graph of the polynomial function
below?

A. The graph has infinitely many zeros.
B. The graph has two zeros.
C. The graph has one zero.
D. The graph has no zeros.

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.
