Question

This question has two parts. First, answer Part A. Then, answer Part B.

Part A CONSTRUCTION Teddy is building the rectangular deck shown. x + 6; x - 2

a. Write an equation representing the area of the deck y

What is the equation of the axis of symmetry?
x =

Part B . Graph the equation and label its vertex.

Answer 1

a.

y = (x+6) (x-2)

=x^2-2x+6x-12

=x^2+4x-12

=(x+6) (x-2)

b. x = (-6) (or) x=2
