Let f(x) be a differentiable function for -3

Let f@) be a differentiable function for -3 x 1. Over this interval f@) has exactly one critical point at x = 0 where f (0) 4. We also know that f (3) 1 and f(l) = 2. Which of the following must be true? Select one: O There is a global maximum, but we cannot determine what it is based on the information given. O The global maximum value of f(x) over the interval is 4. O The global minimum value of f(x) over the interval is -3. O There is no global maximum over this interval.
