Use the graph to create a function with the following features:
1) As x gets smaller; the function approaches negative infinity. x→ - ∞; f(x)→ -∞
2) As x gets larger; the function approaches negative infinity. x→ ∞; f(x)→ -∞
3) The graph of the function passes through the x-axis at -2.
4) The graph of the function passes though the y-axis at y=4
