The y-intercept is (0,-4). The x-intercepts are (-2,0) and (2,0). The degree is 2. End behavior: as x \rightarrow- \infty , f(x) \rightarrow \infty , as x \rightarrow \infty , f(x) \rightarrow \infty .

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.
