The vertical line that can be drawn through the vertex of the parabola so that the bisected halves of the parabola are mirror images of each other is called the

• Mirror Line

• Symmetry

• Axis of Symmetry

• Reflector

How do you calculate the axis of symmetry?

• x = -b/(2a)

• y = -a/2b

• x = -b/a

• x = b/(2a)

Xing and Xia started a small business that makes microwavable tea pods.  Each pod costs $1.00 to manufacture.  The fixed costs are $1500.  They have determined the demand function to be q = -1000p + 8500, where p is the price for each pod. 

The expense equation in terms of DEMAND is

• E = -1000p + 8500

• E = q + 1500

• E = -1000p + 1500

• E = 1500 + 85000

The expense equation is a

• Parabola

• Cubic
