When values of a quadratic function are listed in a table with x-values having a constant difference, the y-vlaues will have a constant (non-zero) second-difference.

Here, we can list first and second differences for the values in the given tables to identify the quadratic function.

Table 1.

  • 1st differences: 3, 3, 3, 3
  • 2nd differences: 0, 0, 0, 0 . . . . this is a linear function

Table 2.

  • 1st differences: -6, -2, 2, 6
  • 2nd differences: 4, 4, 4 . . . . this is a quadratic function

Table 3.

  • 1st differences: 5, -8, -3, -3
  • 2nd differences: -13, 5, 0 . . . . can be described by a 4th degree polynomial

Table 4.

  • 1st differences: 3, 0, -3, -3
  • 2nd differences: -3, -3, 0 . . . . can be described by a 4th degree polynomial

___

The appropriate choice is Table 2.

The population of bald eagles in Forest National Park is declining at a rate of 14% per year. The following expression represent
neonofarm [45]

We know that the population is declining at a rate of 14% per year.

The expression is:

N ( x ) = 206 * ( 0.86 ) ^ x

where x stays for years.

If we want to find the rate at which the population is declining per month we have to find:

\sqrt[12]{0.86} = 0.9875

And 0.9875 ≈ 0.99

There are 12 months in a year so the exponent is: x/12

Answer:

b. ( .99 ) ^ x/12
