Answer:
a) For the function , the parameter for the growth factor is 1.25
c) For the function , the parameter for the decay factor is 50%.
d) For the function y = 18x + 72, the parameter for the average rate of change is 18.
Step-by-step explanation:
We are given the following in the question:
a) the parameter for the growth factor is 1.25.
Comparing it to
The growth factor is
Thus, the given statement is true
b) the parameter for the beginning value is 75.
We are given the equation
The beginning value is given when x = 0. Putting value, we get
Thus, the beginning value is 250.
Hence, the given statement is false.
c) the parameter for the decay factor is 50%.
Comparing it to
The growth factor is
Thus, the given statement is true
d) the parameter for the average rate of change is 18.
Comparing to general form of equation:
where m is the slope and gives the average rate of change.
Thus, the average rate of change is 18.
Hence, the given statement is true.
