Answer:

1) x = 0, x = 1

2) x = -0.387 , x = 1.721

Explanation:

3x² - 3x + 2 = 2

To convert this into the given graph, subtract 3 from both sides, you get

3x² - 3x - 1 = -1

You can find the x values for y = -1 to solve the given equation.

At y = -1, x = 0, 1

3x² - 3x - 1 = x + 1

To solve for this, add a straight line y = x + 1 on the same graph and look for the point of intersections

You'll see the line and the graph meet at two points:

x = -0.387 and x = 1.721
