Find the zeros of y = x2 - 8x - 3 by completing the square.

O A. X= +13
O B. X= 3 ± √7
O C. X= -4±√19
O D. x = 4±√19

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.
