Solve the compound inequality 6b < 42 or 4b + 12 > 8.

b < 6 or b > 5
b < 7 or b > −1
b < 7 or b > 1
b > 6 or b < 5

I think its b based off of my work that i did

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.
