Answer: Average rates of change for Bird A is 0.045 and for Bird B is 3.816.
Step-by-step explanation: Through its graph, a function can be analyzed and be identified its attributes. Average Rate of Change is the ratio of change in the function values to the change of x-value, i.e., it is the slope of the function in a specific interval of x. With the Average it is possible to compare two function.
Average Rate of Change
Bird A:
For the interval [0,18]:
x₁ = 0 f(0) = 8.3
x₂ = 18 f(18) = 9.1
Average = [tex]\frac{f(18) - f(0)}{x_{2} - x_{1} }[/tex]
Average = [tex]\frac{9.1 - 8.3}{18 - 0}[/tex]
Average = 0.045
Bird B: y = 3.6(1.06)x
For the interval [0,18]:
x₁ = 0 y = 3.6(1.06)0 = 0
x₂ = 18 y = 3.6(1.06)18 = 68.7
Average = [tex]\frac{f(18) - f(0)}{x_{2} - x_{1} }[/tex]
Average = [tex]\frac{68.7 - 0}{18 - 0}[/tex]
Average = 3.816
The Average Rate for Change for Bird A is 0.045 and for Bird B is 3.816. This means that the population of Bird B increase in rate faster than the population of Bird A.
