Alg 1 Flashcard 8. Graphing Quadratic Functions in Vertex Form

Front

What is the vertex form of a quadratic function?

Front

How do you find the vertex from the vertex form of a quadratic function?

Front

What does the 'a' value in the vertex form indicate about the parabola?

Back

The 'a' value indicates the direction and width of the parabola. If 'a' is positive, the parabola opens upwards; if 'a' is negative, it opens downwards. The larger the absolute value of 'a', the narrower the parabola.
