Quadratics: Vertex Form

What is the vertex form of a quadratic equation?

The vertex is the point (h, k) in the equation.

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

The vertex is (1, 5).

How do you convert the standard form of a quadratic equation to vertex form?

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

Changing 'k' shifts the graph vertically. If 'k' increases, the graph shifts up; if 'k' decreases, it shifts down.

The parabola opens downwards because 'a' is negative (-3).
