If the graph of the following parabolais shifted one unit left and two united what is the resulting equation in vertex form?
x^2=12y

A.(x + 1)^2 = 12(y-2)
B. (x - 1)² = 12(y+2)
C.(x+2)^2=12(y-1)
D. (x - 2)² = 12(y+1)

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.
