Using the graph, determine any relative maxima or minima of the function and the intervals on which the function is increasing or decreasing. Round to three decimal places when necessary.f(x) = x3 + x2 - x + 1

Question

A. relative maximum: 0.684 at x = 0.549; relative minimum: 2.056 at x = -1.215; increasing  decreasing   
B. relative maximum: 2.056 at x = -1.215; relative minima: 0.684 at x = 0.549 and 1 at x = 0; increasing  decreasing   
C. relative maximum: 2.056 at x = -1.215; relative minimum: 0.684 at x = 0.549; increasing   decreasing 
D. no relative maxima or minima; increasing   decreasing
