• Vertex Form

• Factored Form

• None of These

If you were trying to identify transformations, which form is the most convenient?

• Standard Form

• Vertex Form

• Factored Form

• None of These

• (h, k)

• (-h, k)

• (h, -k)

• (-h, -k)

Which of these goes with each form?

There are 2 Standard Forms. Put the answer choices that alphabetically come first or second to get this correct.

• CANNOT distribute coefficient for this!

• Standard Form

  (second)

• Used for quadratic formula & discriminan

• Standard Form

  (first)

• Vertical Motion Model is a type of this.

• Factored Form

• Also known as intercept form.

• Vertex Form

To find the vertex from Factored Form:

(reorder the steps)

• Plug this value into the original equation.

• Use the midpoint formula on the roots

• Solve & you have the y-value.

• Solve & you have the x-value.

In Standard Form, the shortcut​ (a)   can be used to quickly find the ​ ​ (b)   .

You ​ (c)   plug into the equation & solve to find the entire vertex. ​

• (-b) / (2a)
• STILL NEED TO
• a
• x-value
• DO NOT NEED TO
• y-value
• (-a) / (2b)
• (-2b) / (a)
• (-2a) / (b)
• y-intercept

You need to know the vertex to state the​ (a)   which comes from the x value of your vertex.

You also need to know the Vertex to state the ​ (b)   which comes from the ​ y value of your vertex. ​

• Axis of Symmetry
• Range
• a
• y-intercept
