Based on the graph, what are all of the solutions of x^3+x^2-9x-9=0

The solutions of given equation are -3, -1, and 3

You move the constant to the right side and change its sign to be 9z= -6 -8. that’s the first step.the second step would be calculate the difference of -8-6 to get -14. you equation should now be 9z=-14the last step is to divide both sides by 9 to get z=-14/9hope this
