Read each question carefully and provide your answers in the space provided. For graphing questions, use the coordinate plane. Show all your work.
1. Which of the following describes the end behavior of the polynomial function f(x) = -2x^3 + 5x - 1?
As x → ∞, f(x) → ∞; as x → -∞, f(x) → -∞
As x → ∞, f(x) → -∞; as x → -∞, f(x) → ∞
As x → ∞, f(x) → ∞; as x → -∞, f(x) → ∞
As x → ∞, f(x) → -∞; as x → -∞, f(x) → -∞
