Question 1 Report

The table below is drawn for a graph \(y = x^3 - 3x + 1\).

\(x\) \(-3\) \(-2\) \(-1\) \(0\) \(1\) \(2\) \(3\)
\(y = x^3 - 3x + 1\) \(1\) \(-1\) \(3\) \(1\) \(-1\) \(3\) \(1\)

From x = -2 to x = 1, the graph crosses the x-axis in the range(s)

Answer Details
If the graph of y = x3 - 3x + 1 is plotted,the graph crosses the x-axis in the ranges -2 < x < -1 and 0 < x < 1
