Step 1
Use a graphing calculator to graph
\(\displaystyle{f{{\left({x}\right)}}}={x}^{{{3}}}+{3}{x}^{{{2}}}-{4}{x}-{2}\)
The x-intercept are \(\displaystyle{\left(-{3.9},{0}\right)},{\left(-{0.4},{0}\right)}{\quad\text{and}\quad}{\left({1.29},{0}\right)}\)
The y -intercept is \(\displaystyle{\left({0},-{2}\right)}\)
