Output

To be a function, the DOMAIN, the X-COORDINATE, and the INPUT VALUES cannot repeat.

For example, the coordinates (3,6) and (5,6) are good, but if you were to have the coordinates (3,7) and (3,9), that would not be a function.

Answer:

$4034.40

step-by-step explanation:

the perimeter of the field is the sum of the lengths of the four sides:

47 yd + 158 yd + 47 yd + 158 yd = 410 yd

the cost of 3 ft (1 yd) of fence is 3×$3.28 = $9.84.

so the cost of jake's wood perimeter fance is

(410 yd) × ($9.84 /yd) = $4034.40
