Use the average rate of F of change from t=6 to t=9 to approximate F'(8) I choose t=6 and t=9 because this interval [6,9] includes t=8

OpenStudy (studygurl14):

but the average of 6 and 9 is 7.5, not 8

OpenStudy (freckles):

do you know how to find the average rate of change?

OpenStudy (freckles):

aka the slope of a secant line

OpenStudy (studygurl14):

yes

OpenStudy (studygurl14):

does it matter that the average will find approximately for F(7.5), and not F(8)?
