The polynomial below is a perfect square trinomial of the form A2 - 2AB+ B2. 9x2-12x+4

A. True
B. False

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.

Hi richellerichy in the house and um idk the answer sorry x.x
