Graphing Vertex Form Quadratics

Front

What is the vertex form of a quadratic equation?

Front

What does the parameter 'a' in the vertex form affect?

Back

The parameter 'a' determines the direction and width of the parabola. If 'a' is positive, the parabola opens upwards; if 'a' is negative, it opens downwards.

How do you find the vertex from the vertex form equation?

What is the effect of changing 'h' in the vertex form?

Back

Changing 'h' shifts the graph horizontally. If 'h' increases, the graph shifts to the right; if 'h' decreases, it shifts to the left.

What is the effect of changing 'k' in the vertex form?

Back

Changing 'k' shifts the graph vertically. If 'k' increases, the graph shifts upwards; if 'k' decreases, it shifts downwards.

How do you determine the direction of a parabola from its equation?

Back

The direction of a parabola can be determined by the sign of the coefficient 'a' in the vertex form. If 'a' is positive, it opens upwards; if negative, it opens downwards.
