3. In biology, trophic levels demonstrate the amount of energy that is transferred from one organism to another as shown in the
diagram below.
Level 1
Level 2
Level 3
Level 4
100.00 J
12.00 J
1.44
0.17
In this example, only 0.17 joules of the 100 joules of energy
produced by the pea plant are eventually transferred to the hawk.
Which function below most accurately demonstrates the amount of
energy passed from one trophic level to the next for every 100
joules of energy?
A. f(x) = 0.12(100)
B. f(x) = 100 - (0.12)
1
C. f(x) = 100(0.12 - x)
D. f(x) = 100(0.12)

Part A

x⁴ + 2

You know this is in standard form because the powers of x decrease from left to right.

Part B

The closure property tells you that when you perform the operation (subtraction) on two members of the set (polynomials), the result is also a member of the set (a polynomial).

Example: (x³ + 2x) - (2x +1) = x³ -1

The difference of the two polynomials is also a polynomial.
