ok.. today was our first day in school after having our vacation.. and our teacher instantly gave us assignments. It says:

a. Give descriptions of functions
b. Definitions of functions
c. Examples of functions and give at least 5 each

I looked it up on the wikipedia but i dont really know what to do.. and i still have a blur idea about functions.. Pit please help.!! and thanks in advance

What subject?

In that case:

y = 3x^2 +x

Would be y defined as a function of x.

A function could be described as one value described in terms of another.

thanks.. but i really need a much deeper explanation.. could you suggest any website directing to explanations about funcitons? aside from wikipedia of course..

Not really, that's from my understanding of it.....

From google:

http://en.wikipedia.org/wiki/Function_(mathematics) (I know you said no wiki, but it's pretty decent)

http://mathforum.org/library/drmath/sets/high_functions.html

Hope they help.

functions are just f(x) replacing y in the equation. IE-> f(x)=2x + 1


this person is right, the only different kinds i can think of are.

polynomial ... f(x) = (x+1)^n
linear ... f(x) = x+2
logarithmic f(x) = ln x
exponential f(x) = e^x
trigonomentrical f(x) = sin x

hope that helps
