Rectangle ABCD has vertices of A at (0,0), B at (3.0), Cat (3,-2), and D at (0, -2). After a dilation with a scale factor of 3 and center of dilation at the origin, the image A'B'C'D' is formed. What is the length of side C'D'?​

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.

What is the rest of the question?
