B.
(4, 0), (-1, 3), (9, 1), (-1, 5)

C.
(4, 4), (-1, 2), (9, 1), (-7, 2)

D.
(4, 4), (-1, 6), (4, 3), (-7, 2)

A

Step-by-step explanation:

If there are two points that are the same y value then it is not a function. So in answer a (9,1) and (4,1) have the same y value and so would not pass the vertical line test and is not a function.

maximum area = xy = (16)(32) = 512 ft2

to maximize the area of the garden, the side of the fence parallel to the side of the house should be 32 ft long, and the other two sides should both have length 16 ft.'
