4 Mark all of the statements that are true.
D A. This graph is not a function because the value of yis the same for
every value of x.
O B. All real numbers are in the range of this function.
C. The domain for this function is the set {-5).
D. The range for this function is the set {-5).
I E. The domain for this function is all real numbers.

What are the choices

It’s d for sure i just did also that’s why

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.
