What if one apple has a worm in it; does that make it more valuable or less valuable? What do I get if I try to add one apple and one orange? Two fruits? Well why, then, not start out by saying, "we're going to add this fruit to this fruit"? Why does math ignore quality? It is therefore an incomplete, insufficient science?

Determine if either the function is even odd or neither than describe its symmetry

f(x) = x^6-2x^2+3

h(x) = x^3-5

g(x) = x^3-5x

a)
find lim x---> +infinity of f(x)
b)
find lim x---> -infinity of f(x)
c)
identify all horizontal asymptotes

all this without using a calculator?

Well the equation is

3(x^3) - x + 1
----------------- divided by
x+3

So, how are we suppose to do this without using a calculator. What exactly does x --> infinity / -infinity mean?

Most importantly, how the heck do we find the horizontal asymptotes of such equation?

*this is not homework, studying for my test*

The name of the game is to find the time between consecutive instances when the second hand and the minute hand of a clock coincide. This has to be done in relation to angular speed.

I've defined the angular speed of the second hand as:
ω = 2π/60 = π/30

Angular speed of the minute hand has been defined as:
ω = 2π/3600 = π/1800

The fare for riding a cab is as follows $2.00 for the first mile or part, $0.25 for each additional mile or part.

Determine C(d) an equation representing the cost C of the ride in terms of the distance traveled.

For d≤1, C(d)=?
For d>1, C(d)=?
How much does it cost for a 40 mile ride?

Assuming the person is 17 m tall what is the actual width of the rock?

Can you show working please.

*Can you please explain some of the relationships between log and natural log...I'm confused about when I use natural log in expressions like the inverse of f(x)=e^x/7e^x?
*Also, how do I find the exact value of each expression such as arctan(sqrt3), or sin-1(-sqrt3/2)?
Explanations on this concept in general are welcome, too!

Can't thank you enough.
