OpenStudy (anonymous):

oh i thought u were a friend of mines

OpenStudy (anonymous):

lols an online friend

hero (hero):

Yo Mario

OpenStudy (anonymous):

greetings

hero (hero):

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

OpenStudy (anonymous):

i did do that

OpenStudy (anonymous):

i got 523 but thats wrong

hero (hero):

What happened?

hero (hero):

Let me do it

hero (hero):

I get Average Rate of Change is 0.53

hero (hero):

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

OpenStudy (anonymous):

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
