wrong
I apologize for the mistake. Let me correct it:
To solve the equation x^2 - 9 = 0 by graphing, you would graph the function y = x^2 - 9 and find where the graph intersects the x-axis.
The equation x^2 - 9 = 0 can be factored as (x - 3)(x + 3) = 0.
Setting each factor to zero gives x - 3 = 0 and x + 3 = 0, which results in x = 3 and x = -3.
Therefore, the solutions to the equation x^2 - 9 = 0 are x = 3 and x = -3.
