If f is a continuous function. f(-2) = 3 and f(1) = 6. Which of the following is guaranteed by the Intermediate Value Theorem? Of(c) = 0, for at least one value of c E (-2, 1). Of(c) = 0, for at least one value of c E (3, 6). Of(c) = 4, for at least one value of c E (3, 6). Of(c) = 4, for at least one value of c E (-2, 1)
