Find the Roots (Zeros) f(x)=-3x^3+4x^2+8x-4

$f (x) = - 3 x^{3} + 4 x^{2} + 8 x - 4$

Step 1

Set $- 3 x^{3} + 4 x^{2} + 8 x - 4$ equal to $0$ .

$- 3 x^{3} + 4 x^{2} + 8 x - 4 = 0$

Step 2

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

$x \approx - 1.35667385, 0.43602675, 2.25398043$
