What is the equation of this graph? It is a cosine needing something along the lines of y=acos(b(x-c))+d

Describe a situation that you could represent with the inequality x< 17

Choose the linear inequality that describes the graph. the gray area represents the shaded region. a: y ≤ –4x – 2 b: y > –4x – 2 c: y ≥ –4x – 2 d: y < 4x – 2

If sin(x) = 0 and cos(x) = 1, what is tan(x)?
