What is the gcf of 14x 2 and 4xy?
a. 10x
b. 28x 2y
c. 2x 2
d. 2x

Its D because GCF is a shared factor
14x^2 and 4xy share the greatest factor of 2x

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.
