$f (x) = - x^{7} - x^{6} - 3 x^{5} - x^{3} + 9 x^{2} - 9 x - 8$

Step 1

Set $- x^{7} - x^{6} - 3 x^{5} - x^{3} + 9 x^{2} - 9 x - 8$ equal to $0$ .

$- x^{7} - x^{6} - 3 x^{5} - x^{3} + 9 x^{2} - 9 x - 8 = 0$

Step 2

Graph each side of the equation. The solution is the x-value of the point of intersection.

$x \approx - 0.55107149$
