Consider U = {xlx is a real number}.
A= {x|x EU and x + 2 > 10)
B = {x|x EU and 2x > 10}
Which pair of statements is true?
5€ A; 5 EB
6 EA; 6 #B
8€ A; 8 EB
O 9 EA; 9 # B

Y’all got to do it all over

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.
