What is the name of the math function that looks like a hill?

I am trying to graph my hypothesis on a graph. The program that I am using goes my functions and formulas. I am new to the whole physics thing and I was hoping someone would know the name of a function that looks like a hill... Thanks for all your help!

What is the name of the math function that looks like a hill?
(x,y) / 2-D graph :


y = - x^2 (the simplest, but x^2's multiplier must be less than 0).


y = ax^2 + bx + c, with a %26lt; 0





(x,y,z) / 3-D graph :


z = - cosh (r) = - cosh [鈭?x^2 + y^2)]





the above answers are for "a" hill, but for hills in 2-D, you got y = asin bx + c , or y = acos bx + c
Reply:If it has a sharp point at the top, try an absolute value equation, like y = |x|.





If it is rounded, use a Gaussian distribution (sometimes called a bell curve or a normal distribution) : see http://en.wikipedia.org/wiki/Gaussian_fu... .


This function can be modified in different ways to produce different "hills".
Reply:Quadratic function or parabola.
Reply:-x^2


upside down parabola
Reply:a sine wave
Reply:pi
Reply:bell curve maybe?
Reply:Try the sine curve from [0 degrees to 180 degrees].





I have taken the liberty of providing you with the data values which that covers: I can't graph this for you in Yahoo Answers.
