Answer:

Step-by-step explanation:

a) x = 1.786 & -1.120

Step-by-step explanation:

Turning points are points where the derivative equals zero. Solving the derivative for the values of X will give the answer to part a.

The derivative of this equation
x^3 =x^2-6x[/t[tex]  is [tex]3x^2+2x-6.

Solving the equation
3x^2+2x-6=0 using the quadratic formula we get 1.786 & -1.120

b) x = -3, x=0 and x=2

Explanation:

The solution to this equation are the points where the graph intersects with the x axis. Looking at the graph we can see that these points are -3 , 0 and 2
