Final answer:
Use a graphing calculator to find the x-intercepts of the equation 2x³ – 8x² + 9x – 9 = 0, which are the real solutions, rounded to two decimal places.
Step-by-step explanation:
To find the real solutions of the equation 2x³ – 8x² + 9x – 9 = 0 using a graphing device, you would input the equation into the graphing calculator and use the zero function to locate the x-intercepts of the graph, which correspond to the real solutions of the equation.
These x-intercepts, rounded to two decimal places, are the solutions you are looking for. It's important to note that you will not be able to use the quadratic formula directly since this is a cubic equation, but the graphing calculator can provide an accurate graphical method to find these zeros.
