Find the Coordinates of the Vertex of the Graph Guidance for Casio ClassPad

Find the vertex from the graph of the function.

Step 1

Click on the lowest or highest point on the parabola. That point is called the vertex.

Compare the vertex $(h, k)$ with the vertex form of the function $y = {(x - h)}^{2} + k$ .

$y = {(x - (- 3))}^{2} + (1)$
