Joshua was sketching the graph of the functions f(x) and g(x). He lost part of his notes, including the equations for the functions. Given the partial information below, sketch each function.

The domain of f is \mathbb{R}.

\displaystyle \lim_{x\to \infty} f(x) = -\infty and \displaystyle \lim_{x\to -\infty} f(x) = -\infty

The y-intercept is 2. The x-intercepts are -1, 3, and 5. There is a local extrema at x = 3.
