Question 988799: Can you please help me with this problem?
Determine the average rate of change of the function between the given values of the variable.
f(t)=7/t
t=a, t=a+h
The formula confuses me and I'm not sure where to start. Can you help me solve this?
Thanks! Answer by solver91311(24713) (Show Source):
The average rate of change of a function is defined as the slope of the secant line between two points of interest on the graph of the function.
If you select a point on the function and then choose an amount of change in the independent variable of , then the new point will be . The average rate of change will be the slope of the line that passes through these two points.
Recall the formula for the slope of a line:
where and are the coordinates of the given points.
Compare this to the average rate of change formula:
See illustration
.
For your given function, just plug into the formula:

My calculator said it, I believe it, that settles it
