The graphs below are both quadratic functions. The equation of the blue graph is F(x) = x2. What is the equation of the red graph?
G(X) = ?
F(x) = x2
O
A. G(x) = 1 x
B. G(x) = x2 - 3
C. G(x) = x + 3
D. G(X) = 3x?

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.

Ibelieve the answer is b. y=0 would make the line horizontal across the x.
