I have no idea how to solve for any of these angles.

Use the graph to determine the range. which notations accurately represent the range? check all that apply. (–∞, 2) u (2, ∞) (–∞, –2) u (–2, ∞) {y|y ∈ r, y ≠ –2} {y|y ∈ r, y ≠ 2} y < 2 or y > 2 y < –2 or y > –2

The graph below represents the number of dolphins in a dolphin sanctuary. select all the key features of this function.

F(n + 1) = f(n) – 8. if f(1) = 100, what is f(6)?
