Answer:
The average rate of change is -3
Step-by-step explanation:
we have
This is a linear function in slope intercept form
where
m is the slope
b is the y-intercept
In this problem
The slope is equal to
Remember that
In a linear function the average rate of chance is a constant and is equal to the slope of the linear function in any interval
therefore
The average rate of change is -3
Answer:
= 8 - 11n
Step-by-step explanation:
These are the terms of an arithmetic sequence with n th term
= a + (n - 1)d
where a is the first term and d the common difference
here a = - 3 and
d = - 14 - (- 3) = - 14 + 3 = -11, thus
= - 3 - 11(n - 1)
= - 3 - 11n + 11
= 8 - 11n
