IM2 Functions 1 Review

• Concave Up

• Concave Down

Which equation do I use to find the Axis of Symmetry when the equation is in Standard Form?

• $x=\frac{\left(r_1-r_2\right)}{2}$

• $x=-\frac{b}{2a}$

 $x^2+14x+24$  

What is the Axis of Symmetry for the equation?

• x = -14

• x = -7

• x = -12

• x = -2

 $x^2+14x+24$  

What is the domain of this function?

• $x\ge-7$

• $x\ge-25$

• No Domain

• All Real Numbers

 $x^2+14x+24$  

What are the x-intercepts?

• x = -12 & x = -2

• x = 12 & x = 2

• (-12,0) & (-2,0)

• (12,0) & (2,0)
