Question 7 • GA-Algebra: Concepts and Connections CR

The width of Maya’s poster is 2 inches shorter than the length. The graph models the possible area (y) of Maya’s poster determined by its length (x).Which value of x makes sense for the length of Maya’s poster?

Answer
A
x < 0
B
x < 2
C
x > 0
D
x > 2

Explanation

If the poster’s length is x inches, its width is x − 2 inches. For a real poster, both dimensions must be positive, so x − 2 > 0, which means x > 2. Therefore, the length must be greater than 2 inches, choice D.
