FDT. Given a function f(x) defined in a neighborhood of a critical point x = C, the first derivative test states that: O if f'(x) 0 for x > c, then x = c is a relative minimum O if f'(x) > 0 for x 0 for x > C, then x = c is a relative maximum O if f'(x) > 0 for x C, then x = c is a relative minimum O if f'(x) c, and f'(c) = 0, then x = c is a relative maximum Off'(x) > 0 for x 0 for x > c, and f'(c) = 0, then x = cis a relative maximum O none of the other answers Oif '(x) > 0 for x 0 for x > c, and '(C) = 0, then x = c is a relative minimum O if (x) 0 for x > c, then x = c is a relative maximum Off'(x) c, and f'(c) = 0, then x = c is a relative minimum >
