2.7 The Derivatives and Rates of Changes Flashcards
1
Q
how do you find when a particle moves to the right on a position function?
A
- note when the position function increases so on positive slopes
- state the time intervals of increase
2
Q
how do you find when a particle moves to the left on a position function?
A
- note when the position function decreases so on negative slopes
- state the time intervals of decrease
3
Q
how do find the average velocity?
A
use the formula f(x)=f(x2)-f(x1)/x2-x1
4
Q
how to find the instantaneous velocity?
A
use the formula f(x)=f(x2)-f(x1)/x2-x1
its the same formula to average velocity just between a smaller distance
5
Q
how to determine whether a limit exists
A
use the formula f(x)=f(x2)-f(x1)/x2-x1
