Simplify, step by step please: [(1/(x+h)^3) - (1/x^3)] / 15h
this is horrid...
are you talking about my question domian and range
you have not given a function there prodgers
the domain andrange of f (-2) of f(1)
for this one you need to make a common denominator for x^3 and (x+h)^3
so what would be the answer I am so confused with this mess. I have not taken this kind of mathe in 20 yrs
\[(x^3 - (x+h)^3 )/(x^3 * (x+h)^3)\]
prodgers2, go back to your question and look at what I typed....
so is that the range or the donmain
by the way is this for a limit?
Nope, no limit
and the above is still divided by 15h (x+h)^3=x^3+3x^2h+3xh^3+h^3
so the x^3 will cancel
and the h too
\[(3x^2+3xh+h^2)/(15(x^3 * (x+h)^3)\]
oh no, there is a minus sign in front of this
yes and it is asking to write the answer in interval notation
and I dont see how you can simplify it further
\[[(1/(x+h)^3) - (1/x^3)] / 15h = 0 \] ???
akiroso is that the range or domain?
prodgers2, it's neither, this is not your problem.
THANKS ANDRAS!!! XD
