Learn how to analyze the graphs of quadratic functions using a vertex form. The vertex is a minimum for an upward opening parabola, and it's a maximum for a downward opening parabola. Using this form, we can easily see what the vertex of the quadratic function is, and therefore we can easily see its axis of symmetry. The coefficient of the quadratic term determines the direction that the graph opens and the shape of the parabola, and it is possible to write the vertex form from the standard form of the quadratic equation.
*These practice questions are only helpful when you work on them offline on a piece of paper and then use the solution steps function to check your answer.
