What is the average rate of change for ƒ(x) = −3x + 1 over the interval −2 ≤ x ≤ −1?
2 answers:
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
