Mathematics - 17 October 2006

t (s): 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11
x (s): 0, 5, 20, 45, 80, 90, 100, 100, 100, 100, 80, 60

1. find the greatest speed. I don't know which one it is since there are 4 points of "100"
2. least speed? Do I count "0" or"1"?
3. the speed is constant? would I choose 6, 7, 8,9?
4. average speed of particles for the first 7 s?
5. find the instantaneous speed of the particles at 3s.

Could someone explain all of this to me?

Does anybody know how these equations are done? Here are a few more examples:

g (x) = x^2 + 7.5
g (x) + (52x)^2
g(x) = -2x^2

The function

F(x,y)=x^3+y^3-12(x+y)+6xy Has a minimum near (1.1,1.1)

How do I find this minimum? I know how to work out a function with one variable but two is giving problems.
