In calculating the average rate of a function, which of the following statements holds TRUE?

Question

Choices:

A. Finding the slope of a tangent line between any two points in a function.

B. Finding the average value between any two points in a given function.

C. Finding the derivative of a graph at any given interval.

D. Finding the slope of the secant line between any two points in a function.

Answer 1

definitely B., the average.value

to find average value of function, we calculate the area created by function and x-axis

between point a and point b on x-axis. b>a. Then the area is divided by (b-a). That value

is in "units" of f(x) and is the average value of f(x) from x=a to x=b.
