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 largest possible value of b is 3*1 = 3.

Sorry, I'm afraid that's not correct.
