Sketch a graph of $y = 1 - x^3$. Then complete the following approach statements. .

1. As $x → ∞$, $y$ approaches?

   Hint (a):

   As $x → ∞$, the $y$-values keep going down.

   Answer (a)

   As $x → ∞$, $y→−∞$

2. As $x → −∞$, $y$ approaches?

   Hint (b):

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

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

   Hint (c):

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