Intro to Quadratics

Simplify by combining like terms:
 $5a\ +2b-3a+4$  

•  $8a+2b+4$  

•  $2a_{ }+2b+4$  

•  $8ab$ 

•  $4ab+4$  

Which of the following equations matches standard form of a quadratic? HINT: use your foldable!

• $Ax+By=C$

• $y=a\left(x-h\right)^2+k$

• $y=Ax^2+Bx+C$

• $y=mx+b$

What is the domain of the function?

*Hint: Domain is the set of all x-values included in the function.

• $x\ge3$

• $x\le3$

• $all\ real\ numbers$

• $-1\le x\le5$

The graph of a quadratic function is called a

• Parabola
• Vertex
• Axis of Symmetry 
• Vertex Form

Identify the 'b' value:  $y=16x^2-8x-24$  

•  $16$  

•  $-8$  

•  $8$  

•  $-24$  

Identify the 'a' value:  $y=16x^2-8x-24$  

•  $16$  

•  $8$  

•  $-8$  

•  $-24$
