Examine the intersection of these two lines: 2 lines intersect to form 4 angles. From the top, clockwise, the angles are 1, 4, 2, 3. Which pairs of angles are adjacent? Select all that apply. ∠1 and ∠2 ∠1 and ∠3 ∠1 and ∠4 ∠2 and ∠3 ∠2 and ∠4 ∠3 and ∠4

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.

8-2x+3x2=6 and six is your answer
