mm ya looks fine so far :o

OpenStudy (anonymous):

okay yay! so the next part asks this: what is the average rate of change of f(x) between x=1 and x=3? what do i do here? and it's round to two decimal places:)

zepdrix (zepdrix):

The average rate of change over that interval will be the `change in y` / `change in x`

OpenStudy (anonymous):

so f(3)-f(1)/3-1 ? =(e^3)-(e^1)/2 ??

zepdrix (zepdrix):

Mmm ya looks good!

OpenStudy (anonymous):

=8.68 ?

zepdrix (zepdrix):

yes

OpenStudy (anonymous):

yay:) and this is the next part: use average rates of change to approximate the instantaneous rate of change of f(x) at x=2. round to one decimal place what do i do here?

OpenStudy (anonymous):

**last part for this problem!!**
