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 table of values, also known as a 'T chart'.

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.
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.
