Q.10. - 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.$3x^4- x^3+ 4x^2 - 5 = 0$

Step-by-Step Solution

Answer

The values of X are approximately$x\approx \hspace{0.17em}0.93688\dots ,\hspace{0.17em}x\approx \hspace{0.17em}-0.84568\dots$

Step 1. Given equation

$3x^4 - x^3 + 4x^2- 5 = 0$

Step 2. Graph and X- intecepts

X-intercepts are $x\approx \hspace{0.17em}0.93688\dots ,\hspace{0.17em}x\approx \hspace{0.17em}-0.84568\dots$
