  1. Sketch a graph of y = 1 − x3. Then complete the following approach statements. 1-57 HW eTool (Desmos). Homework Help ✎

    1. As x → ∞, y approaches?

    2. As x → −∞, y approaches?

    3. As x → 0 (from the left), y approaches?

As x →∞, they-values keep going down.

As x →∞, y→−∞

As x →−∞, do the y-values go up, down, or do they level off to a horizontal asymptote?

Follow the curve towards x = 0 from the left of that point. What y-value do you predict?
