The number of users on new social media site increase as 21, 25, 30, 36,
The average rate of change is given by 5.
The function f (t) = 12 (1.2) ^t show how the rate of users increases in weeks.
<h3>What is Average?</h3>
Average of the values is the ratio of total sum of values to the number of values.
Here, f (t) = 12 (1.2) ^t is defined in the range of (3, 6)
So the value of the function in its range is given by
1) f (3) = 12 (1.2) ^3
= 21
2) f (4) = 12 (1.2) ^4
= 25
3) f (5) = 12 (1.2) ^5
= 30
4) f (6) = 12 (1.2) ^6
= 36
Now the average rate of change = sum of all difference in values at every week / max. Difference in interval of range(3,6)
= f(6)-f(3)/6-3
= 15/3
= 5
Thus required average change of rate is 5.
