The polynomial function is a cubic polynomial function with a general equation of y = ax^3 + bx^2 + cx + d. a is given to be -1. roots make y = 0
when x = 1
y = -1(1) + b + c + d = -1 +b+c+d = 0
when x = 2
y = -1*8 + 4b + 2c + d = -8 + 4b+c+d = 0
when x =k
y = -k^3 + k^2b + kc + d = 0
when x = 3, y =8
8 = -27 + 9b + 3c + d
<span>b=7/3 , c=23/3 , d=−9
</span>k1<span> = 9.3556</span>
k2<span> = -2.71051</span>
k3<span> = 0.35491</span>

Answer:
17.30 dollars
Step-by-step explanation:
Given that Payton and James mow the lawns.
They do this during summer.
The amount they spend are:
Gas cost = 3.50
Leaf bags = 1.20
Add these to get total costs
Total cost = 4.70
Charge they get per lawn = 22.00
Profit = Revenue - cost
Here revenue per lawn = 22 and cost per lawn = 4.70
Hence profit = 22-4.70 = 17.30 dollars.
Answer is they make 17.30 dollars per lawn.
