Q.9 - Precalculus Enhanced with Graphing Utilities

Question

In Problems 5–16, use a graphing utility to approximate the real solutions, if any, of each equation rounded to two decimal places. All solutions lie between - 10 and 10.$x^4- 2x^3+ 3x - 1 = 0$

Step-by-Step Solution

Answer

The approximate value of $x\approx \hspace{0.17em}0.35855\dots ,\hspace{0.17em}x\approx \hspace{0.17em}-1.11768\dots$

Step 1.Given equation

$x^4- 2x^3+ 3x - 1 = 0$

Step 2. Graph and X-intersections

X-intercepts are $x\approx \hspace{0.17em}0.35855\dots ,\hspace{0.17em}x\approx \hspace{0.17em}-1.11768\dots$
