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!

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)=

So-called "scientists" claim that dinosaurs roamed the earth a million years ago, but there is proof that they existed only a few thousand years ago! There are footprints in Mexico where dinosaurs and humans walked side by side. Since we know humans came to North America only a few thousand years ago, that proves dinosaurs were around then, too.

This is yet another hole in the thoery of evolution. Even scientists agree that it is full of holes!

Given the following data:
CaO(s) + CO2(g) → CaCO3(s) ΔH = -178.3 kJ
2Ca(s) + O2(g) + 2CO2(g) → 2CaCO3(s) ΔH = -1626.9 kJ

Find the ΔH of the following reaction:
2Ca(s) + O2(g) → 2CaO(s)

Given the following data:
S(s) + O2(g) → SO2(g) ΔH = -296.8 kJ
CS2(l) → C(s) + 2S(s) ΔH = -89.4 kJ
CO2(g) → C(s) + O2(g) ΔH = +393.5 kJ

Find the ΔH of the following reaction:
CO2(g) + 2SO2(g) → CS2(l) + 3O2(g)

I have been noticing this a lot lately. I bumped into an old girlfriend lately, but before I saw her.. I saw her boyfriend who I had not yet met and thought immediately of her (like I saw her face in him... strange I know). She then came up behind him and I realised it was her boyfriend.

The Jetscream amusement park ride at wonderland is shown here: http://www.pcwjunkies.com/pcw/flatrides/jetscr.htm

It starts off by swinging like a simple pendulum until its amplitude becomes so great that it swings completely around. If the diameter of the circle is 30.0m, what speed must the ship have at the very bottom to just make it to the highest point and sit there with no residual speed?

(use Energy formula- E_k = 1/2mv^2 & E_g=mgh)
