Given a polynomial f(x)=(x-1)(x+7)(x+3), is this in factored form? If not, put in factored form and answer the following. a) What are the solutions?
b) What does f(1)=0 mean?
c) What are the x-intercepts?

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.
