It is known that for a function f(x), f'(1) = 0 and f" (1) = -0.5. What does the Second Derivative Test say, if anything, about the function at x = 1? O There is a relative max at x = 1. O There is a relative min at x = 1. O There is a point of inflection at x = 1. O The test is inconclusive at x = 1. There is a singular point at x = 1
