____
of y = 3x 3 + 15x 2 − 12x − 60. If necessary, round to the nearest hundredth.
A relative minimum: (–62.24, 0.36), relative maximum: (37.79, –3.69),
zeros: x = 5, –2, 2
B relative minimum: (0.36, –62.24), relative maximum: (–3.69, 37.79),
zeros: x = –5, –2, 2
C relative minimum: (0.36, –62.24), relative maximum: (–3.69, 37.79),
zeros: x = 5, –2
D relative minimum: (–62.24, 0.36), relative maximum: (37.79, –3.69),
