Solving Polynomial Equations by Graphing

Use a graphing calculator to solve the equation by graphing. If necessary, round to the nearest hundredth. $$x^3 - 9x^2 + 27x = 20$$ What is the value of x?

Use a graphing calculator to solve the equation by graphing. If necessary, round to the nearest hundredth. $$x^6 - 15 = 5x^4 - x^2$$ What is the approximate value of x?

Use a graphing calculator to solve the equation by graphing. If necessary, round to the nearest hundredth. $$\frac{1}{2}x^5 = \frac{1}{5}x^2 - 2$$ What is the approximate solution?
