(x) denotes subscript
Statement:
F(0)= 1 F(1)= 1 F(2) = 2 F(3) =3 .... denotes the fibonaccia numbers. Then for n > 1, (F(n)F(n+2))^1/2 is irrational.

And does a similar result hold for the number (F(n))^1/2

How Can I Write This Recursive Definition (this is pretty hard, I think)?!?!?

I have been working on this for a while and can't figure it out. It has been really troublesome for me. Any help would be appreciated.

Suppose that n people numbered 1 to n are lined up with their backs to a wall. Starting at the end of the line, eliminate every other person until only 1 survives. Reverse directions when you reach the end of the line. For example, for n=10, the elimination order is 2,4,6,8,10,7,3,5,1 so the survivor is 9. Let s(n) denote the survivor's number (hence S(10)=9). Find a recursive definition for S(n). You should have a base case and 2 recursive cases-- one for S(2k) and S(2k+1).

Differentiable Function?

I need some help, please! :[

Well, I need to determine the values of x at which a certain fuction is differentiable. Do I just graph it on my calculator? Or is there an algebraic method?

The equation is:
y= square root (x^2 + 9)

Thank you so much, I really appreciate it!

If youre told to plot a graph of temp. as a function of volume, does it mean temp. is the dependent variable?

and volume is therefore the independent variable?

discontinuity help!!! Plz explain how to get answer!!?

A function f(x) is said to have a removable discontinuity at x=a if:
1. f(x) is either not defined or not continuous at x=a.
2. f(a) could either be defined or redefined so that the new function IS continuous at x=a.
Let f(x) =\frac{2x^2+3 x -5}{x-1}
Show that f(x) has a removable discontinuity at x=1 and determine what value for f(1) would make f(x) continuous at x=1.
Must define f(1)=
