🛎️ Vertex Form of a Quadratic
- The vertex form is y = a(x − h)² + k, and the vertex is (h, k).
- For example, in y = 2(x + 3)² − 1, the vertex is (−3, −1).
🛎️ What Do h and k Mean?
- h moves the graph left or right.
- k moves the graph up or down.
🛎️ Shifting a Parabola Using Vertex Form
- Start with y = 2x², which has its vertex at (0,0).
- Moving the vertex 3 left and 1 down gives the new graph y = 2(x + 3)² − 1.
