Consider the following equation 1
Approximate the solution to the equation above using three iterations of successive approximation. Use the graph below as a starting point. HELP

$4034.40

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

the first one is x^2+2x+2

the second one is x^2+4

the last one is x^2-4x+8
