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

Short 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-by-step solution

Step 1.Given equation

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

Step 2.  Graph and X-intersections

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