y = 2x + 3 is a function rule. This rule can also be written in several different ways:
f(x) = 2x + 3 "f of x equals ...', or f: x -> 2x+3 "f maps x as ...".
As a set of ordered pairs. Here is a set of pairs which satisfy our function, f: {(1,5), (2,7), (3, 9), (4, 11)}.

A rule is a way of describing a function in words. Conversly, a function is simply a way of describing mathematical rules in numbers and symbols.

A linear function is a function whose graph is a straight line.
Oh honey, a quadratic function is a function whose rule is a polynomial of degree 2. It's like the middle child of polynomials - not too simple, not too complex, just right. So next time you see that squared term, you know you're dealing with a quadratic function, sweetie.
Well, look for a continuing pattern. Once you find one that makes sense for each value, write it into an equation....look at example below x- 2,4,6,8 y- 4,16,36,64 the rule for this function is y=x squared.

Measurement of length.
You need to give an example of the rule and the function you want.

Different cells have different appearences because they have different functions. A good rule of thumb is the "form follows function" rule.

What its guts look like and how they function
You can write them any way you like, as long as the basic definition of "function" is maintained. Basically, this means that the function must be defined uniquely defined for every input.
