Find the Coordinates of the Vertex from a Table Guidance for Casio ClassPad

Find the vertex of $y={(x-2)}^{2}$.

Step 1

Open the table for the function. Add higher $x$-values into the table. How could you know, without looking at the graph, which point you entered in the table was the highest?

Step 2

Add $x$-values, if needed, until you can see the symmetry around the vertex.
