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)}.

What does a linear equation graph look like?
A linear function is a function whose graph is a straight line.
A quadratic function is a function whose rule is a polynomial of degree what?
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.
