For a function f(\(x\)), suppose that you know that f(-= -2 and that f(= 2. What would you need to know about \(f\) in order to invoke the Intermediate Value Theorem to conclude that there is at least one zero of \(f\) on [-1, 3][the closed interval from negative 1 to 3]?
\(f\) IS CONTINUOUS ON [-1, 3] (ACCEPT: F IS CONTINOUS ON THE INTERVAL)
