precalculus? or no?

you should do 1  (1 + 3h + 3h^2 + 3h^3) first

do i just get rid of the first round bracket?

cruffoBest ResponseYou've already chosen the best response.1
correct. Distribute the  through [1 1*( everything inside parenthesis) ]

sorry had to step away..

correct: \[\frac{ [1(1+3h+3h^2+3h^3)](2) }{ h } = \frac{ [113h3h^23h^3]2 }{ h }\]

but I'm curious: did you originally have to do 1(1+h)^3 in the top?

well i have this equation: \[y=1x^3\] and i need to find the average slope of the line passig through A (1,2) and Δx=h

burhan101Best ResponseYou've already chosen the best response.1
so that was what i came up with

I think before you go any further, there is something that need to be corrected.

cruffoBest ResponseYou've already chosen the best response.1
Here x = 1, so you want \[f(1+h) = 1(1+h)^3 = 1[(1)^3 + 3(1)^2h + 3(1)h^2 + h^3\] \[ = 1(1+3h3h^2+h^3)\] So the top would be \[\frac{ [1(1+3h3h^2+h^3)](2) }{ h } = \frac{ [1+13h+3h^2h^3]2 }{ h }\]

burhan101Best ResponseYou've already chosen the best response.1
then the 2 would cancel out with 2

burhan101Best ResponseYou've already chosen the best response.1
and we would factor out the h ?

cruffoBest ResponseYou've already chosen the best response.1
hah. right. those pesky negatives...

burhan101Best ResponseYou've already chosen the best response.1
but my text book says the final answer is: \[h2+3h3\] :S :S

cruffoBest ResponseYou've already chosen the best response.1
just rearrange the terms in decending order in h

burhan101Best ResponseYou've already chosen the best response.1
ohh it's the same thing .. :$ LOL i thought it was different haha :$

burhan101Best ResponseYou've already chosen the best response.1
thankyou so much :D !

burhan101Best ResponseYou've already chosen the best response.1
if part b says to calculate slope for h= 10,2,1,1/2 do i find the limits for his @cruffo ?
 one year ago

cruffoBest ResponseYou've already chosen the best response.1
Should just be able to plug in the numbers for h in you previous answer, \[\large h^2 + 3h  3\]
