Estimate the x-coordinates at which the relative maxima and relative minima occur for the function. f(x) = 4x3 + 11x2 + 5

A) The relative maximum is at x = 1.83, and the relative minimum is at x = 1.
B)The relative maximum is at x = –1.83, and the relative minimum is at x = 0.
C) The relative maximum is at x = –1.83, and the relative minimum is at x = 1.
D) The relative maximum is at x = 1.83, and the relative minimum is at x = 0.
