Which statement is true about the graphed function?

a. f(x) < 0 over the interval (–∞, –4)

b. f(x) < 0 over the interval (–∞, –3)

c.(x) > 0 over the interval (–∞, –3)

d.(x) > 0 over the interval (–∞, –4)

B-simple yes/no questions

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.

The best answer is 2lbs
