Learn how to use the parent graph to graph a quadratic with transformations

The video tutorial explains how to graph quadratic equations in vertex form by identifying key components such as H, K, and A. It covers plotting the axis of symmetry, identifying the vertex, and determining the graph's opening direction. The tutorial emphasizes understanding graph shape and translation without stretching, providing tips for accurate graphing.

What are the components you need to identify in vertex form?

• M, N, and O

• X, Y, and Z

• H, K, and A

• A, B, and C

How do you determine the axis of symmetry in vertex form?

• Y = B

• X = A

• Y = K

• X = H

What does the value of 'a' determine in the graph of a quadratic function?

• The height of the graph

• The width of the graph

• The direction the graph opens

• The color of the graph

If 'a' is equal to -1, what can be said about the graph?

• It opens upwards

• It opens downwards

• It is a horizontal line

• It is a vertical line

What happens to the graph if there is no vertical or horizontal stretch?

• It retains its original shape

• It disappears

• It becomes narrower

• It becomes wider

What is a useful tip when graphing with 'a' equal to 1 or -1?

• Ignore the vertex

• Use the same shape as the original graph

• Change the axis of symmetry

• Alter the vertex coordinates

How do you reflect a point when graphing a quadratic function?

• Move it downwards

• Move it to the left

• Move it upwards

• Move it to the right
