Yardbird landscaping has 52 m of fencing with which to enclose a rectangular garden. if the garden is x meters long, express the garden's area as a function of the length.

f(L)=-L²*26L

Step-by-step explanation:

Let's start by looking at the formula for a rectangle's perimeter (which is what the fencing implies):

When the question asks for the garden's area as a function of the length, it's basically saying "whatever value is in the function (as in f(value) ), make that value be the length."

But first we have to find L*W, because that's the function of the area.

1.) Solve for W

2.) Plug in W for the function L*W

hello from mrbilldoesmath!

answer:

the domain is the set { -2, 0, 2, 3}

discussion:

the domain is the set of x values in the ordered pairs (x,y). taking the x, or first component, of each ordered pair gives   -2, 0, 2, 3.
