Question 330056: How can you find the solutions of a quadratic equation by looking at a graph. How do you find the vertex?

The solutions (the zeros) are the x-values where the function crosses the x-axis (equals zero).
You find the vertex by completing the square and putting the equation into vertex form, where (h,k) is the vertex.
