(this is multiple choice and i raised the points explain )

what is the difference of r and s?

a) (r-s)(x)= -x+4
b) (r-s)(x)= x-4
c) (r-s)(x)= x-2
d) (r-s)(x)= x+2

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.

Where is the picture
