Writing and interpreting quadratic functions

Write the following quadratic expression in completed square or vertex form.

x² + 4x + 10

• (x + 4)² + 6

• (x + 2)² + 6

• (x + 4)² - 6

• (x + 2)² - 6

What is the vertex form of the quadratic function?

• f(x) = ax² + bx + c

• f(x) = a(x-h)² + k

• f(x) = a(x+h)² - k

• f(x) = x²

What form is the quadratic equation written in?

y = (x - 2)(x + 4)

• Factored Form

• Standard Form

• Vertex Form

• Linear Form

Convert the quadratic equation $y\ =\ x^2\ -\ 2x\ +\ 5$  
into vertex form. 

•  $y\ =\ \left(x\ -\ 1\right)^2\ -\ 6$  

•  $y\ =\ -\left(x\ -\ 1\right)^2\ -\ 6$  

•  $y\ =\ \left(x\ +\ 1\right)^2\ -\ 6$  

•  $y\ =\ \left(x\ +\ 6\right)^2\ -\ 6$  

Write the following quadratic expression in vertex form

x² + 14x + 50

• (x + 7)² + 1

• (x - 7)² - 1

• (x - 7)² + 1

• (x + 7)² - 1

Which quadratic function in vertex form can be represented by the graph that has a vertex at (-3, 4) and passes through the point (0, 0).

What form is f(x)=(x+1)(x-2)?

• Standard

• Factored

• Vertex

What is the formula for Vertex Form?

• y = a ( x - p ) ( x - q )

• y = a ( bx - h )² + k

• y = ax² + bx + c

What is the equation graphed below?

Type your answer like this:

y=a(x-h)^2+k

(you put in the correct values of a, h, and k)

There are 2 form have intercept and don't have vertex.
