Graph x^3 - 3x^2 + 2 = 0.1 - x What are the solutions of the equation?
liq [111]

Answer:

x=-0.6,x=1.52,x=2.08

Step-by-step explanation:

Let f(x)=x^3-3x^2+2.

and

g(x)=0.1-x

The graph of the two equations are shown in the attachment.

The points where the two graphs intersected are: (-0.6,0.7),(1.52,-1.42),(2.08,-1.98)

The x-coordinates of the intersection points are the solutions to x^3-3x^2+2=0.1-x.

Therefore the solutions are: x=-0.6,x=1.52,x=2.08
