1) You are given the following set.
{(-4, 4), (-2, 2), (0, 0), (2, 2), (4, 4)}
(a) If the set defines a function, find the domain.
The domain is made of the x-values ...
Domain: -4,-2,0,2,4
(b) If the set defines a function, find the range.
The range is made of the y-values ...
Range: 4,2,0
2) The perimeter of a rectangle is 20 inches. Express the area A(w) as a function of the width w.
2w + 2l = 20
2l = 20 - 2w
l = 10 - w
A(w) = wl
A(w) = w(10 - w)
A(w) = 10w - w^2
