Suppose that $f(x)$ and $g(x)$ are functions on $\mathbb{R}$ such that the range of $f$ is $[-5,3]$, and the range of $g$ is $[-2,1]$. The range of $f(x) \cdot g(x)$ is $[a,b]$. What is the largest possible value of $b$?

The upper bound is given when f(x) is $-5$ and g(x) is $-2$, which when multiplied equals $\boxed{10}$
