Question 1000816: This is at the end of our chapter where we learned about arithmetic and geometric sequences and the binomial theorem. The question is: Expand the binomial in the difference quotient and simplify. I'm given [f(x+h)-f(x)] divided by h, I'm then given f(x)=x cubed. I don't get how this relates to series, sequences, their sums, or finding the Nth term, if you could explain the connection as well, I would appreciate it so much.

"... and the binomial theorem." You mostly need to expand that part in the difference quotient, specifically this part of the expression:

and refer directly to the binomial theorem formula to be really formal about this. To be simpler about this, .

I do not see how this relates to series, sequences, their sums, or finding the Nth term either.
I see how this relates to algebra in general, and polynomials in particular, and
I see how this is a sneaky introduction to derivatives,
which would belong in an early calculus lesson.
If the name of your class is pre-calculus, a sneaky introduction to derivatives may be the purpose of this problem.
is the slope of the line AB that passes through points
and of the graph of .
As you decrease towards zero, points A and B get closer together,
"tending to" being the same point A, and the line AB tends to being the tangent to the curve at A.
The derivative of is the function
