All you have to do is just evaluate H(2) and H(2.01) then do
H(2.01) - H(2)/2.01 - 2
hero (hero):
average rate of change = slope

Try that and see what happens
OpenStudy (anonymous):
ok thats right... what did you do to get that?
hero (hero):
There is a general formula for average rate of change. It is very similar to the slope formula
OpenStudy (anonymous):
yes i know
OpenStudy (anonymous):
i think the square roots messed me up

hero (hero):
Yeah, probably
OpenStudy (anonymous):
i got 2.8 from the first and then 8.03 from the second
hero (hero):
Well, just to let you know, 2.01 is not that far from 2, so the values that you get shouldn't be that far off
OpenStudy (anonymous):
so 8.03-2.8/2.01-2=5.23/0.01=523
hero (hero):
The values I got were:
(2.8373 - 2.8243)/(2.01-2) = .53

i didnt square 8.03
OpenStudy (anonymous):
even when i square it though, i still get the wrong answer for some reason.
hero (hero):
You're not supposed to even have ever gotten 8.03
OpenStudy (anonymous):
yes i was... 3(2.01) + 2 = 8.03
OpenStudy (anonymous):
i got the right answer now though
