Find the difference quotient and simplify answer: f(5+h)-f(5)/h, h cannot = 0
ok this is what i did and i got stuck.
??????? help me out...its getting so late can't keep my eyes open lol
The function is defined as follows :
Basically, you are trying to simplify this :
It is equivalent to (by substituting the function into your expression) :
Expand this :
Further expansion required ...

Factorize with :
Finally, cancel out the , to find :
And you are done
EDIT : ah Defunkt you win, I was busy checking my reply :/
