Solution
Let’s break the question into parts and analyze step by step:
-
Functions Overview:
- : This is a linear function.
- : From the table, the values of (dependent on ) are provided:
.
Notice that is decreasing non-linearly.
-
Average Rate of Change: The average rate of change of a function between two points and is given by:
-
First Blank: Interval where the average rate of change of is greater than : For , the slope (rate of change) is constant and equal to (the coefficient of ).
Calculate the average rate of change of over intervals and compare with :- From to :
- From to :
- This shows that the rate of change of is consistently less than .
Answer: The average rate of change of is not greater than on any interval provided.
- From to :
-
Second Blank: As increases, the average rates of change of and :
- has a constant rate of change ().
- has a decreasing rate of change (as shown above, rates are negative and stay constant).
Answer: The average rates of change of and remain constant, respectively.
-
Third Blank: When , the value of :
- Using the trend of , the table stops at , where .
- Assuming continues its trend, you can extrapolate to find :
From to , decreases by . Thus, would decrease by another :
Answer: When , .
-
General Statement: An exponential function (e.g., doubling growth) will eventually exceed any linear function because exponential growth accelerates at an increasing rate.
Final Fill-in-the-Blanks:
- Over the interval none, the average rate of change of is greater than the average rate of change of .
- As the value of increases, the average rates of change of and remain constant, respectively.
- When the value of , the value of is 0.
- It can be further generalized that a quantity increasing exponentially will exceed a quantity increasing linearly.
