Question

The graph y=3x^2 - 3x -1 is shown.

Use the graph to find the solution to the equations:

Answer 1

Explanation:

3x^2 - 3x + 2 = 2 subtract 3 from each side of the equations

3x^2 - 3x -1 = -1 see image below ....look at the red line ( y = -1) where it crosses the blue graph are the solutions ( the 'x' values)

3x^2 - 3x -1 = x+1 This one is a bit difficult using just the graph....see second image
