A biologist studied the populations of geckos and salamanders at Huntington Beach State Park over a five year period The biologist modeled the populations, in thousands, with the following polynomials where x is time, in Geckos: 9.77-0.8+23
Salamanders: - 1. 12° +7.72 +5.4
What polynomial models the total number of geckos and salamanders at gntington Beach State Park?
8.62? +6.9.r - 7.7
O 8.622-6.9.r +7.7
8.6 + 6.9 +7.7
8.62 - 6.9z - 7.7

  b.   the average rate of change of f(x) is less than the average rate of change of g(x).

step-by-step explanation:

since the length of the interval is the same in each case, we only need to compare the change in y-value to see which is greater.

so the change in y-value for function f is (6 )) = 9.

the table tells us

so the change in y-value for function g is (31 -1) = 30.

the change in y-value of f(x) on the interval is less than the change in y-value of g(x) on the same interval, so the average rate of change of f(x) is less than the average rate of change of g(x).
