Graphing Quadratics in Vertex Form

What happens to the graph of a quadratic if the absolute value of 'a' is greater than one?

• It becomes wider.

• It becomes narrower.

• It shifts to the left.

• It shifts to the right.

If 'a' is negative, how is the graph of the quadratic affected?

• It becomes wider.

• It reflects vertically.

• It shifts downwards.

• It shifts upwards.

What does the 'h' value in the vertex (h, k) represent?

• The direction of the graph.

• The width of the graph.

• The horizontal shift.

• The vertical shift.

In the vertex form of a quadratic, what does the 'k' value indicate?

• The width of the graph.

• The vertical shift.

• The direction of the graph.

• The horizontal shift.

For a quadratic with a vertex of (1, 2) and an 'a' value of 1, what is the next step after plotting the vertex?

• Go out two units and up one unit.

• Go out two units and down one unit.

• Go out one unit and down one unit.

• Go out one unit and up one unit.
