The area A of a rectangular garden is given by the expression2^2+ 2 − 12. The length L of the garden is
given by the expression x2 - 9. Find an expression for the width W of the garden. (Recall that A = LW). What
are the excluded values in this calculation and what do they represent in context?

Step-by-step explanation:

We have that the area of a rectangular garden is

and the length of the rectangular garden is

We want to find an expression for the width W of the garden.

From A=LW, we have

We factor to get:

Since this is a rational function, there is a hole at x=-3 and a vertical asymptote at x=3. These are the excluded values.
