Vertex Form of Quadratics

Front

What is the vertex form of a quadratic equation?

Front

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

Back

The parameter 'a' 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.

What is the significance of the vertex in a parabola?

Back

The vertex is the highest or lowest point of the parabola, depending on whether it opens upwards or downwards.

Front

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

Back

Changing the value of 'h' shifts the parabola left or right. If 'h' increases, the parabola shifts to the right; if 'h' decreases, it shifts to the left.

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

Back

Changing the value of 'k' shifts the parabola up or down. If 'k' increases, the parabola shifts up; if 'k' decreases, it shifts down.
