The table below is drawn for a graph y = x3 – 3x + 1
(begin{array}{c|c} x & -3 & -2 & -1 & 0 & 1 & 2 & 3 \hline y = x^3 – 3x + 1 & 1 & -1 & 3 & 1 & -1 & 3 & 1end{array})
From x = -2 to x = 1, the graph crosses the x-axis in the range(s)
(begin{array}{c|c} x & -3 & -2 & -1 & 0 & 1 & 2 & 3 \hline y = x^3 – 3x + 1 & 1 & -1 & 3 & 1 & -1 & 3 & 1end{array})
From x = -2 to x = 1, the graph crosses the x-axis in the range(s)
